	* lisp/gpelcard.tex: Corrected "pm3d" instead of "mouse".

2004-04-14  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/version.c: Activate "RELEASE_VERSION" code by inserting a
	#define.
	(HELPMAIL, CONTACT): Provide fall-back definitions.

	* src/show.c (show_version): Update splash text for better

2004-04-13  Ethan Merritt  <merritt@u.washington.edu>

	* term/x11.trm: If gnuplot_x11 dies, or fails to start, then make
	sure all locks on the [now defunct] pipe are cleared.

2004-04-13  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* PATCHLEVEL: Reset to zero.

	* VERSION: Updated to 4.0 for the release.

	* All over the place: Removed pointers to mailing lists at
	Dartmouth from all source files.  Updated Copyright statements to
	list 2004 as one of the years.  Changed remaining references to
	mailing lists to the new ones as SourceForge.net.
	
	* docs/gpcard.tex: Small updates to reflect at least the major
	changes since 3.7.
	
	* lisp/README.1st: A new file to explain the relation between this
	directory and the stand-alone gnuplot-mode package made by Bruce
	Ravel.

	configure.in, to avoid strange interactions caused by mixed
	autoconf versions.
	
	* tutorial/.cvsignore: Ignore *.toc files, too.

	* term/gd.trm (PNG_options): Bugfix: font options "tiny"
	... "giant" failed to unset the freetype "font" option.

2004-04-12  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/command.c (do_system) [!USE_OWN_WINSYSTEM_FUNCTION]: disable
	usage of winsystem(), which apparently causes more trouble than
	it's worth.  To re-enable this, manually #define the
	USE_OWN_WINSYSTEM_FUNCTION macro.

2003-04-10  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* INSTALL: Include a notice about the demise of 16-bit versions on
	MS-DOS and Windows.  Updated the paragraph about the history of
	gnuplot-mode.

	* README.1ST: Updated. Added a paragraph about PDFlib licensing.

	* README: Updated to reflect imminent release.  Changed text about
	mailing lists.  Added pointers to the web pages at SF.net.
	Removed some mirrors that don't exist any longer.

	* src/fit.c (Dblfn): Re-initialize va_args between uses.  Needed
	to be C standard compliant and survive running on Linux/AMD64.
	(Fixes SF bug #932162).

2004-04-08  Ethan Merritt  <merritt@u.washington.edu>

	* src/readline.c: Revert patch from 2003-05-10 "Allow <tab>
	characters in input stream." This broke filename auto- completion
	by gnu libreadline. Reversion re-introduces the problem that
	gnuplot's own readline makes it impossible to enter <tabs> in a
	command line.

2004-04-08  Petr Mikulik  <mikulik@physics.muni.cz>

	* TODO: Updated.
	
	* INSTALL: Updated.

2004-04-07  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/set.c (looks_like_numeric): Recognize blanks and other
	special formatting characters in floating point formats correctly.

	* src/save.c (save_set_all): Moved writing of timefmt strings up
	in the list of saved settings, so 'set xtics' can have time/date
	strings as endpoints.

2004-04-05  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* BUGS: Removed lots of long-since fixed bugs.  Updated
	descriptions of some others.  Got rid of numbering --- it was
	completely mixed-up anyway.

	* term/win.trm: Added a note regarding the limitation of no wide,
	patterned lines in Windows terminal.

2004-04-05  Petr Mikulik  <mikulik@physics.muni.cz>

	* BUGS: Removed point "8. contour line clipping of 3D data plots":
	it should go to FAQ or to gnuplot's web page => "Useful
	scripts". Removed point "11. bug in OS/2 emx/gcc 2.7.x optimizer"
	(cite this in makefile.os2). Added link to gnuplot's sourceforge
	bug tracker.

	* config/README: Small update.

	* config/makefile.os2: Mention compiler optimization problem from
	BUGS.

2004-04-04  Ethan Merritt  <merritt@u.washington.edu>

	* term/svg.trm: 'Set term svg {fontfile <filename>}' option to embed a
	font, or a hyperlink to it, in the output svg document. This allows the
	use of symbol fonts in conjunction with enhanced text mode. The file
	search path is controlled by environmental variable GNUPLOT_FONTPATH. 

2004-04-01  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/plot.c: Fix OS/2 release version string if wrong in using
	utsname.h.

	* src/mouse.c: On OS/2, don't start with mouse on by default. For some
	unknown reason, it clashes with arrow keys and even palette color
	allocation in multiplot mode... I guess these strange features are in
	gnuplot for ages, as it was always recommended to put "unset mouse"
	into gnuplot.ini.

	* FAQ: Updated to current version.
	Technote: not used "lynx -dump" from its Makefile (spurious references
	left) but from menu "Save formatted document" in links in xterm with
	80 columns.

2004-03-31  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/graph3d.c (do_3dplot): Ignore "set grid {back|front}" in
	hidden3d mode --- they would directly contradict the idea of
	hidden-line removal.

	* docs/gnuplot.doc (grid): Document effect of hidden3d mode on
	options "back" and "front".
	(border, xtics): Document that "set grid {front|back}" also
	controls the drawing order of border and ticmarks.
	(xtics axis): Describe actual effect of on-axis tics coming too
	close to the graph border.

	* configure.in: New options --enable-h3d-quadtree and
	--enable-h3d-gridbox to control compile-time flags of hidden3d
	code.

	* src/show.c (show_version): Lots of mostly stylistic changes to
	"show version long" part.  Replaced long comma-separated chain of
	assignment statements by individual initialized variable
	definitions.  Added printouts for new feature macros
	HIDDEN3D_GRIDBOX and HIDDEN3D_QUADTREE.  Joined string output by
	fputs into the fprintf() format string.  Broke the list of
	compiler flags into two lines.

	* src/hidden3d.c (HIDDEN3D_GRIDBOX, HIDDEN3D_QUADTREE): Renamed to
	avoid namespace collisions since these are now globally visible.
	Used to be called TEST_GRIDBOX and TEST_QUADTREE.  Changes occur
	all over hidden3d.c.

2004-03-30  Ethan Merritt  <merritt@u.washington.edu>

	* src/axis.c: Fix another case of arithmetic assignment to a
	boolean.

2004-03-30  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/graph3d.c (plot3d_lines_pm3d, plot3d_points_pm3d,
	get_surface_cbminmax): Make local copy of
	plot->pm3d_color_from_column a TBOOLEAN.

	* src/pm3d.c (pm3d_plot): Likewise.

	* src/hidden3d.c (in_front): Simplify by removing almost-boolean
	local variables v{1,2}_inside_p.

2004-03-29  Ethan Merritt  <merritt@u.washington.edu>

	* src/hiddden3d.c: Must not do arithmetic using TBOOLEANs!!!

2004-03-29  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* PATCHLEVEL: Increased for yet another release candidate tarball.

	* src/version.c: Updated accordingly.

	* lisp/.cvsignore: Add autom4te.cache to set of ignored names.

2004-03-29  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* tutorial/Makefile.am.in: Add tutorial.toc to CLEANFILES.

2004-03-29  Per Persson  <persquare@users.sf.net>

	* term/aquaterm.trm: Major update to driver.
	Built if libaquaterm present, requires AquaTerm 1.0 or later.

2004-03-29  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Fix up a blunder exposed by making TBOOLEAN an actual boolean
	type: the TBOOLEAN argument "head" of term->arrow() was misused as
	an integer.
	
	* src/term_api.h (TERMENTRY): Change type of argument "head" of
	function pointer "arrow" to int.

	* src/term.c (do_arrow): Changed type of argument 'head' to int.

	* term/tpic.trm (TPIC_arrow): Likewise.

	* term/tgif.trm (TGIF_arrow): Likewise.

	* term/texdraw.trm (TEXDRAW_arrow): Likewise.

	* term/pstricks.trm (PSTRICKS_arrow): Likewise.

	* term/metapost.trm (MP_arrow): Likewise.

	* term/metafont.trm (MF_arrow): Likewise.

	* term/latex.trm (LATEX_arrow): Likewise.
	(best_latex_arrow): Likewise.

	* term/gpic.trm (GPIC_arrow): Likewise.

	* term/fig.trm (FIG_arrow): Likewise.

	* term/epslatex.trm (EPSL_arrow): Likewise.

	* term/eepic.trm (EEPIC_arrow): Likewise.

	* term/dumb.trm (DUMB_arrow): Likewise.

2004-03-27  Ethan Merritt  <merritt@u.washington.edu>

	* term/svg.trm: Further fixes to enhanced text mode. Revise option
	parsing so that it is not sensitive to the command line order.

2004-03-26  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* config/config.nt: Remove HAVE_STDBOOL_H and HAVE__BOOL again ---
	turns out MSVC doesn't have them.

2004-03-26  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.cyg: Added -DHAVE_STDBOOL_H to the compile
	command for pgnuplot.exe to avoid compiler warnings.

2004-03-25  Ethan Merritt  <merritt@u.washington.edu>

	* term/x11.trm: Prevent wrap-around of ruler coordinates.

2004-03-25  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/gplt_x11.c: References to pipe_died must be surrounded by
	#ifdef PIPE_IPC.

	* config/config.os2: #undefine HAVE_STDBOOL_H and HAVE__BOOL.

2004-03-25  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* config/config.amg config/config.cyg config/config.mgw
	config/config.nt config/config.os2: Added new macros
	HAVE_STDBOOL_H and HAVE__BOOL needed by my change to the TBOOLEAN
	setup in syscfg.h two days ago.

	* src/term.c (curr_arrow_headfilled): Changed type from TBOOLEAN
	to int, because this variable has more than 2 possible values.

	* src/term_api.h (curr_arrow_headfilled): Changed extern
	declaration accordingly.

2004-03-24  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c: Change window size immediately on 'm' toggle.

	* term/gd.trm: Update comments on libgd version requirements.

2004-03-23  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c: If gnuplot exits while "x11 -persist" is active,
	hand over mousing of last active plot to gnuplot_x11. This fixes
	the test case provided with bug #921033.  Also, continue to honor
	'm' key as a toggle for mousing in detached windows.

2004-03-23  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* configure.in (AC_HEADER_STDBOOL): Added call to this macro.

	* src/syscfg.h: Rewrite the definition of FALSE, TRUE and TBOOLEAN
	from scratch, this time based on autoconf's recommendations.  The
	previous version collided with a "#define bool _Bool" found
	somewhere deep in the Mac OS X system headers.

2004-03-23  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/axis.c (t_timelevel): Start enum values at 1, to avoid
	wrap-around of expression TIMELEVEL_SECONDS - 1.
	(make_auto_time_minitics): Fine-tune thresholds and generate tick
	step sizes to get more sensible minor tick steps.
	(quantize_time_tics): Only set timelevel[axis] to a higher value
	if the tic step is at least one unit long.
	(time_tic_just): Remove superfluous update of local variable just
	before exit from function.
	(setup_tics): Handle reverted time/date axes correctly.

2004-03-22  Ethan Merritt  <merritt@u.washington.edu>

	* src/term.c src/gplt_x11.c term/gd.trm term/pdf.trm term/x11.trm
	term/dumb.trm term/post.trm: Revamp the implementation of the '@'
	character (phantom box) in enhanced text processing.  This fixes
	bug #906056 "@-aligned string does not work with font change".
	Basically it adds a save/restore position command to the
	term->enhanced_open() routine, and brackets the @-text with a save
	and restore.  Probably a PostScript guru can beautify my code
	further.

2004-03-21  Ethan Merritt  <merritt@u.washington.edu>

	* term/svg.trm: Add an enhanced text mode for the svg
	terminal. It's not perfect, but it works well enough to overcome
	some of the text formatting limitations in the svg plain text
	mode.

2004-03-18  Ethan Merritt  <merritt@u.washington.edu>

	* term/dumb.trm: Fix segfault on 'unset output' while in dumb
	terminal.

2004-03-15  Hans-Bernhard Broeker  <broeker@ac3b07.physik.rwth-aachen.de>

	* src/axis.c (load_range): Un-set 'reverse' option if fixed range
	specification is given in forward order.

2004-03-12  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* PATCHLEVEL: Raised to 2 for new release candidate.

	* src/version.c: Updated.

	* docs/doc2texi.el (d2t-texi-header): Updated version to 4.0,
	changed "organized by" entry from Dave to Lars.  Added Copyright
	year entry for 2004.

	* docs/titlepag.ms: Likewise.

	* docs/gnuplot.texi: Regenerated.

	* docs/Makefile.in ($(srcdir)/gnuplot.texi): Renamed rule target
	to include $(srcdir).  Fixed copy command to pull gnuplot.doc,
	into build directory, not gnuplot.texi.

2004-03-11  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	The fix for SF bug "[905651] Grid and border overlap the plot".
	This is rather elaborate, unfortunately:

	* src/graph3d.c (USE_GRID_LAYERS): New feature test macro.  Turned
	on automatically for now. If PM3D is on , this is forced on, too.
	(whichgrid): Removed global variable.
	(do_3dplot) [USE_GRID_LAYERS]: Draw back part of grid before the
	plotted data/functions, and front part afterwards, by passing a
	new argument to draw_3d_graphbox().
	(draw_3d_graphbox): Added new argument 'whichgrid' to control
	which parts of the graph box will be drawn.  Default is ALLGRID,
	i.e. draw all of it.  All calls updated accordingly.
	(draw_3d_graphbox) [USE_GRID_LAYERS]: Use new parameter to decide
	which parts to actually draw.  Changed #if PM3D to USE_GRID_LAYERS
	to enable this former PM3D-only code for general usage.
	(xtick_callback, ytick_callback, ztick_allback): Removed former
	PM3D-only checks --- they're done in graphbox now, before calling
	gen_tics().

	* src/pm3d.h (PM3D_HAVE_SOLID): New macro, default value zero.
	Disables pm3d option {transparent|solid}, which is no longer
	needed --- it's a duplicate of what 'set grid front' already
	achieves.
	(pm3d_struct) [!PM3D_HAVE_SOLID]: Remove struct field
	corresponding to disabled option.

	* src/pm3d.c (pm3d) [!PM3D_HAVE_SOLID]: Remove initializer of
	removed struct field.
	(pm3d_reset) [!PM3D_HAVE_SOLID]: Remove operation to clear removed
	struct field.
	
	* src/set.c (set_pm3d) [!PM3D_HAVE_SOLID]: Ignore disabled option,
	warn if running interactively.

	* src/show.c (show_pm3d) [!PM3D_HAVE_SOLID]: Disable display of
	removed option.

	* src/save.c (save_set_all) [!PM3D_HAVE_SOLID]: Disable saving of
	removed option.

	* docs/gnuplot.doc (pm3d): Removed documentation of no longer
	existant option.
	(grid): Document new default layering of 3D grid/boundary.

2004-03-11  Petr Mikulik  <mikulik@physics.muni.cz>

	* tutorial/tutorial.tex tutorial/header.tex: Updates about
	TeX-friendly terminals in gnuplot 4.0.

	* term/gd.trm term/gif.trm: Don't print debugging message.

2004-03-10  Ethan Merritt  <merritt@u.washington.edu>

	* term/cgm.trm: Revise the conditional code sections so that it is
	possible to select USE_ULIG_FILLEDBOXES without PM3D.

2004-03-09  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/os2/gnupmdrv.rc: Renamed menu entry "~data style" to "style
	~data", and same for "~function".

	* config/config.mgw config/config.os2: #define
	HAVE_TIME_T_IN_TIME_H.

	* ChangeLog: Fixed typos and spaces in author names and their
	e-mails in ChangeLog entries.

2004-03-08  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* docs/doc2texi.el: Add @dircategory Math to place the gnuplot
	info file into a suitable place in the master info directory page.

	* docs/gnuplot.texi: Updated accordingly.

2004-03-07  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c: Selecting linetype -2 worked only because bounds
	checking was incorrect.  Now treat LT_BACKGROUND, LT_NODRAW, and
	other negative linetypes as a request for the background color.

	* src/term.c: Allow explicit vertical offset of 0 in enhanced text
	mode overprint statement.  Patch by Harald Harders (SF.net bug
	report #911068).  Overprint positioning remains inexact at best in
	non-PostScript drivers.

2004-03-04  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/axis.h (STORE_WITH_LOG_AND_UPDATE_RANGE): Added check
	against infinities and NaNs.  Most paths were already blocked, but
	modern systems can have "inf" and "nan" right in the datafile,
	which wasn't tested against.

2004-03-03  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* docs/gnuplot.doc (fit): Clarify behaviour in case no "using"
	specification was given.

2004-03-02  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/standard.c (f_tanh): Added extra code to return an exact 1.0
	for large absolute arguments.  Fixes SF bug #908184.

	* term/x11.trm [TERM_HELP]: Explain colour control via command
	line options more clearly, including the -xrm for colors other
	than the background.

	* docs/gnuplot.doc (random, palette): Fixed entries showing up as
	sub-topics in the wrong places of gnuplot.gih.

2004-03-02  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/gnuplot.doc term/x11.trm: Fix entries appearing in 'help
	help'.

2004-02-27  Ethan Merritt  <merritt@u.washington.edu>

	* term/mif.trm: Revise #ifdef so that it compiles if you select
	configure --disable-filledboxes

	* src/gplt_x11.c: Add #ifdef so that it compiles if you select
	configure --disable-pm3d

2004-02-27  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/config.cyg config/config.mgw config/config.os2: Shape
	these config files to the form of config.hin generated by
	./configure. This will more easily facilitate to synchronize
	particular #(un)define options added to the ./configure procedure
	in future.

2004-02-27  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Fix SF bug [ 905691 ] "save" does not save correct arrow heads.

	* src/term_api.h (t_arrow_head): New enum type to provide manifest
	constants for arrow head choices.
	(arrow_head_names): Added declaration of new global in term.c.
	(arrow_style_type): Change type of member "head" from int to new
	enum.

	* src/term.c: Define constant strings for arrow head placement
	options.

	* src/save.c (save_set_all): Use new string constant to correctly
	output head placement options.

2004-02-27  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/gnuplot.doc term/x11.trm: Added missing labels for hypertext
	references.

2004-02-24  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/config.amg config/config.cyg config/config.mgw
	config/config.os2: Changed GP_FIT_ERRVARS from #undef to #define
	(complies with the default value of ./configure).

2004-02-23  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* docs/gnuplot.doc (bind, mouse variables, if, using, label,
	mouse, x11 mouse, pm3d, palette, style arrow, style line): Removed
	help entries that would go directly under 'help'.
	(pm3d): Remove help entries that suggest 'set pm3d' has sub-nodes:
	it doesn't.
	
	* term/vgagl.trm [TERM_HELP]: Removed help entries that would go
	directly under 'help'.

	* term/x11.trm: Likewise.

	* term/pc.trm (PC_move, PC_vector, PC_put_text): Change coordinate
	arguments to unsigned int to match terminal API.

	* src/term.h [DOS386]: Allow DOS386 platforms to load the
	PC-specific driver section, too (--> Watcom).

	* src/plot3d.h: Prepend 'extern' to turn erroneous definition into
	a declaration.

	* src/plot3d.c (plot_has_palette): Moved definition here, from
	src/plot3d.h.

	* src/plot.c (main): Leave at end of main using return statement,
	not the exit() system call.  Exit() confuses compilers that expect
	main to return an int.

	* src/bf_test.c (main): Likewise.

	* docs/doc2tex.c docs/doc2rnh.c docs/doc2ms.c docs/doc2ipf.c
	docs/doc2hlp.c docs/doc2gih.c docs/checkdoc.c (main): Likewise.

	* docs/doc2rnh.c (main): Replace one EXIT_SUCCESS returned on
	error condition by EXIT_FAILURE.

	* config/makefile.wc: Lots of changes to make this ancient
	orphaned file workable with current releases of the Watcom
	compiler.  Will need further files config/config.wc
	src/makefile.awc and to actually work, though.  Converted to Unix
	text file format in CVS.

	* config/README: Converted to Unix text file format.

	* config/config.cyg (HAVE_TIME_T_IN_TIME_H): Add this missing
	configuration item.

2004-02-22  Ethan Merritt  <merritt@u.washington.edu>
	
	* src/gplt_x11.c: When drawing rotated text, only modify pixels
	that actually contain part of the text. Fixes bug #668782.  Patch
	originally submitted by Mike Sutton
	<suttonm@users.sourceforge.net>, lightly modified by me.  NB: This
	code makes refreshing the plot window very slow if rotated text is
	present.  It is particularly noticeable when the window is
	resized.

2004-02-22  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Fix SF bug: [ 666462 ] steps/histeps calculation/display problem.
	
	* src/graphics.c (edge_intersect_steps, ): Replace invidual tests
	against axis range ends by calls to macro cliptorange(), which can
	handle reverted ranges.
	(edge_intersect_fsteps): Likewise.
	(two_edge_intersect): Use GPMAX() of axis endpoints instead of
	axis.max element to compare to, again to avoid surprises with
	reverted axes.
	(do_key_sample): De-ANSI-fied.  Reindented.

2004-02-21  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Tagged a patchlevel 1 to incorporate some post-last-minute
	changes:
	
	* PATCHLEVEL: Incremented by 1 for these post-release changes.

	* src/version.c: Updated.
	
	* configure.in (X11 handling): Append ${EXEEXT} to gnuplot_x11
	program name to allow building on X11 platforms that use .exe
	extensions for programs (Win32, OS/2).

	* config/config.mgw config/config.cyg config/config.os2: Remove
	'#' lines that aren't actual preprocessor commands.

	* src/win/wgraph.c (GraphStart): Don't grab keyboard focus unless
	mouse mode is on.

2004-02-20  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* demo/electron.dem (3rd plot): Use "set key default" to get a
	sensible position of the key.  Without it, it's outside the page
	and you get terminal driver errors.

2004-02-20  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Tagged and released version 3.8k.0, which also serves as release
	candidate #1 for release as version 4.0.
	
2004-02-18  Ethan Merritt  <merritt@u.washington.edu>
	
	* src/readline.c term/x11.trm: Patch by Bill Fenner fixing bug
	#899245, suspend/resume with gnu readline requires us to trap
	EINTR.

2004-02-18  Ethan Merritt  <merritt@u.washington.edu>

	* demo/webify.pl demo/Makefile.am.in: Make output html compliant
	with 4.0.1 transitional standard.  Add enhancedtext.dem to the
	list of auto-generated html pages.

2004-02-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* configure.in (--disable-defined-var): Remove annotation as
	EXPERIMENTAL.
	(--disable-fiterrvars): Changed default to enabled, removed
	annotation as EXPERIMENTAL.

2004-02-18  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/config.cyg config/config.mgw config/config.os2: Added
	#undef GP_FIT_ERRVARS and #define GP_ISVAR.

        * src/plot3d.c: Issue a warning when trying to draw surface with
	pm3d style and there has not been previous "set pm3d".  Maybe we
	could refrain from this requirement in future by adding new field
	'pm3d.on' to 'pm3d.where' in 'struct pm3d'.

2004-02-15  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c src/plot3d.c src/pm3d.c: Trivial changes to
	prevent stupid compiler warnings.

2004-02-13  Ethan Merritt  <merritt@u.washington.edu>

	* demo/prob.dem demo/prob2.dem: pause(-1) after final plot

	* term/svg.trm term/post.trm: Rearrange things slightly so that
	the output code is less ugly (cleanup of my 1 Feb 2004 patch).

2004-02-13  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* config/makefile.nt (makefile.nt, config.h): Copy makefile.nt and
	config.nt over into the src directory, if necessary.

	* src/time.c [!USE_SYSTEM_TIME] (gstrptime): Replace
	implementation of %s format.  Now reads in a double-precision
	number and uses gnuplot's own ggmtime() routine instead of library
	function gmtime().  This should fix SF bug #885279 "Reading '%s'
	timefmt is not 64 bit safe".
	(CHECK_SPACE, COPY_STRING, FORMAT_STRING): Macros moved inside
	function xstrftime() they belong to.  Changed to use do {...} 
	while(0) pattern.  #undef them after use.
 	(xstrftime): Changed return type to size_t to avoid warnings.
	(LETTER, NOTHING): Macros moved into function gstrptime() they
	belong to. #undef them after use.

2004-02-13  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/config.os2: Add SELECT_TYPE_ARG* definitions.

2004-02-12  Ethan Merritt  <merritt@u.washington.edu>

	* src/specfun.c demo/random.dem docs/gnuplot.doc:
	Modify behaviour of rand() function in response to bug report #870706
	    rand(0) returns a pseudorandom number generated from current seeds
	    rand(-1) resets both seeds to a standard value
	    rand(x) for x>0 sets both 32-bit seeds to x
	    rand({x,y}) for x>0 sets seed1 to x and seed2 to y

2004-02-12  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/os2/gclient.c: Let the color sequence of the first 5 line
	types be the same as in postscript.

	* src/term.c (do_point): Let sequence of the 6 defined point types
	be the same as in postscript, png and x11.

2004-02-12  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS src/plot.c src/win/winmain.c src/win/pgnuplot.c
	term/win.trm: Let gnuplot on Windows accept the '-persist' command
	line option (preferred synonym to '-noend' and '/noend').

2004-02-12  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.cyg config/makefile.mgw: Missing copy of file
	VERSION into the latexing directory.

2004-02-01  Ethan Merritt  <merritt@u.washington.edu>

	* term/gd.trm term/post.trm term/pdf.trm term/svg.trm: In the rare
	case of a request to draw a line or polygon-fill with LT_NODRAW or
	LT_BACKGROUND it makes more sense to set the color to white than
	to black.  The x11 terminal already behaves this way.

2004-01-25  Ethan Merritt  <merritt@u.washington.edu>

	* term/gd.trm docs/gnuplot.doc: Take default font for gdlib
	terminals (png jpeg) from environmental variable
	GNUPLOT_DEFAULT_GDFONT.

2004-01-20  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/Makefile.in: gnuplot.tex needs to be latexed 3 times (it
	contains multipage toc).

2004-01-19  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.cyg config/makefile.mgw config/makefile.os2:
	Copy file VERSION into the latexing directory (setting TEXINPUTS
	from within Makefile does not portably work).

2004-01-17  Ethan Merritt  <merritt@u.washington.edu>

	* src/save.c src/save.h src/show.c: Consolidate the save and show
	routines for data and function plot styles into a single place.

2004-01-14  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* Makefile.am: Remove superfluous files from LISP_DISTCLEANFILES.

	* docs/Makefile.in: Add $(top_srcdir) to TEXINPUTS. Add installcheck
	target. Fix uninstall-gih and uninstall-info targets.

	* docs/titlepag.tex: Remove path to VERSION file, this is now taken
	care of by TEXINPUTS.

	* lisp/Makefile.am: Remove superfluous files from DISTCLEANFILES.
	Remove dist-hook.

	* src/Makefile.am: Include PKG_MAJOR in pkglibexecdir. Adjust
	X11_DRIVER_DIR accordingly. New variable pkglibexec_PROGRAMS for
	gnuplot_x11, remove install-exec-local and uninstall-local targets
	as automake creates them for pkglibexec_PROGRAMS.

2004-01-13  Ethan Merritt  <merritt@u.washington.edu>

	* src/save.c: The color axis format was not being saved; now it is.

2004-01-12  Ethan Merritt  <merritt@u.washington.edu>

	* demo/webify.pl demo/mgr.pl demo/polar.dem demo/random:
	Use 'print' rather than 'pause 0' in demos to avoid empty plots.
	Have webify.pl delete empty *.png files on exit. If gpsavediff is
	available, use it to create a script for each plot. If gnuplot.css
	is present, reference it as a stylesheet. 

2004-01-11  Ethan Merritt  <merritt@u.washington.edu>

	* src/command.c, src/term.c, term/x11.trm, docs/gnuplot.doc: 
	Add sanity checks to 'pause mouse' command; give a warning if mousing
	is not active.  For X11, do *not* terminate 'pause mouse' on normal
	input from stdin. This is necessary to allow 'pause mouse' to work
	from piped input since more commands may already be queued up in stdin.

2004-01-10  Petr Mikulik  <mikulik@physics.muni.cz>

	* pm3d.c (geomean4): Support negative values to help splot surfaces with
	all color coordinates negative and "set pm3d corners2color geomean".

	* gplt_x11.c: Print the debugging message "gnuplot_x11 3769: mouse
	button 1 from window 1 at 0 0" only #ifdef DEBUG.

2004-01-08  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* lisp/configure.in: Remove superfluous file copying commands, now
	taken care of by auto* tools.

	* src/gplt_x11.c(pr_window): Bugfix: static array must be computable
	at compile time.

2004-01-07  Ethan Merritt  <merritt@u.washington.edu>

	* src/plot.c, term/x11.trm: Set stdin to unbuffered on program entry
	rather than waiting for the start of an X11 plot. All buffered input
	is lost by the call to setvbuf(), so the only safe time to call it is
	before there is any input. This fixes the latest manifestation of the
	"x11 clipboard paste problem", and also the "piping from awk" problem.

2004-01-07  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* configure.in, configure.vms, src/fit.c, src/gplt_x11.c, src/stdfn.h,
	term/ggi.trm, term/x11.trm: Use AC_FUNC_SELECT_ARGTYPES instead of
	AC_FUNC_SELECT and related changes.

	* config/config.amg: Updated.

	* docs/gnuplot.doc: Removed whitespace-only line as pointed out by
	"make check".

	* m4/apple.m4, m4/beos.m4, m4/msdos.m4, m4/next.m4: Newer autoconf
	versions require stricter quoting.

2004-01-07  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* term/x11.trm (X11_args) [!USE_MOUSE]: Don't try to parse
	"-nofeedback" option if mousing disabled.

	* src/command.c (test_palette_subcommand, test_time_subcommand):
	Made static; added missing local prototype.
	(test_palette_subcommand): Changed static const int "colors" to an
	enum to make it eligible as an array size under C90.  Renamed to
	"test_palette_colors" to avoid global name space contamination.
	Made several local string constant variables 'static', and removed
	a superfluous one. Reindented.

2004-01-06  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* demo/Makefile.am.in: Add webify.pl to distribution.

2004-01-01  Ethan Merritt  <merritt@u.washington.edu>

	* configure.in: Fix incorrect nesting of libpdf status test.

2003-12-29  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/util3d.c (polyline3d_next): Bugfix. The patch on 2003-12-19
	broke contouring in hidden3d mode.  polyline3d_previous_vertex
	wasn't updated.

2003-12-26  Jim Van Zandt  <jrv@debian.org>

	* src/set.c (load_tic_user): user tic definition can have 3rd
	token specifying minitic

	* src/axis.h: ticmark.level specifies major or minitic

	* src/axis.c (gen_tics): Request user-supplied minitics

	* docs/gnuplot.doc: document user-supplied minitics

2003-12-24  Ethan Merritt  <merritt@u.washington.edu>

	* src/show.c: Fix buffer overflow in conv_text() if the text
	contains many characters with the high bit set.

	* demo/enhancedtext.dem: Add demo for enhanced text mode.

	* demo/charset.dem: Add demo that displays font and character
	encoding.

2003-12-21  Ethan Merritt  <merritt@u.washington.edu>

	* term/post.trm src/gplt_x11.c src/set.c src/term_api.h
	src/term.c: Add support for ISO-8859-15 character encoding.

	* docs/gnuplot.doc: Minor changes to What's New.

2003-12-21  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/x11.trm: Add missing #ifdef PIPE_IPC.

	* term/pm.trm: Remove useless declaration.

2003-12-19  Ethan Merritt  <merritt@u.washington.edu>

	* term/svg.trm: Sodipodi didn't care that the namespace URL was
	junk, but the Adobe svg viewer doesn't like this. Give it the real
	URL.

2003-12-19  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/util3d.h (polyline3d_start, polyline3d_next): Prototypes
	added.

	* src/util3d.c (draw3d_line_unconditional): Avoid re-doing the
	linetype change if it's to the same as in the lp_style_type
	already applied.
	(polyline3d_previous_vertex): New static variable.
	(polyline3d_start, polyline3d_next): New functions. Draw connected
	polylines in 3D.  Hidden3d currently disables this --- to be added
	in later.  Polylines can't change colour in the middle of a run,
	so palette mode turns this optimization off, too.

	* src/graph3d.c (cntr3d_lines): Use new helper routines to draw
	connected polyline instead of isolated segments.
	(do_3dplot): Since cntr3d_linespoints would break polyline
	handling, call cntr3d_lines() and cntr3d_points() in a row,
	instead.
	(cntr3d_linespoints): Now unused --> #if'ed out.

2003-12-16  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c term/x11.trm: Add a new x11 command line option
	-nofeedback, and the corresponding Xresource gnuplot*feedback.  It
	disables the feedback loop by which gnuplot_x11 reports font and
	plot size information back to gnuplot via the mouse pipe. This is
	a work-around for feedback synchronization problems triggered by
	certain scripting environments and possibly by other causes under
	os2.

2003-12-16  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/gnuplot.doc: Changes in "What is New in 4.0".

	* src/mouse.c (bind_display): Minor change in the hotkey help.

	* term/post.trm (START_HELP): Fixed undefined references in
	gnuplot.tex.

	* src/gplt_x11.c: #if (USE_MOUSE && MOUSE_ALL_WINDOWS) => #if
	defined(...) && defined(...)

2003-12-15  Ethan Merritt  <merritt@u.washington.edu>

	* demo/Makefile.am.in demo/webify.pl demo/airfoil.dem
	demo/prob2.dem: Integrate generation of demo web pages into the
	Makefile, so that 'make html' autogenerates most of them.  A few
	oddball scripts need to be processed by hand.

2003-12-15  Ethan Merritt  <merritt@u.washington.edu>

	* term/svg.trm: Lauris Kaplinski <lauris@users.sourceforge.net>
	diagnosed that the reason gnuplot point styles were not displaying
	properly in some svg applications was our failure to specify the
	xlink: namespace.

	* term/post.trm: PS_filled_polygon() must flush current path on
	entry if there is one.  This fixes the missing arrow-shaft
	problems seen in arrowstyle.dem.  It is possible that the awk
	scripts in pm3d/contrib need to be modified to parse the resulting
	"stroke" command.

2003-12-15  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.os2: Lowercased IF EXIST and DEL commands (there
	is a make.exe program reported to dislike uppercases).

2003-12-15  Petr Mikulik  <mikulik@physics.muni.cz>

        * src/gplt_x11.c:
        (getMultiTabConsoleSwitchCommand): New routine to return system
	command to switch to the appropriate "tab" of a multitab console
	window where gnuplot is running. Currently implemented for KDE's
	Konsole (it returns a "dcop" command).
        (process_event): Let hotkey "<space>" in gnuplot_x11 work also in
	gnuplot running in multitab KDE's Konsole.

2003-12-15  Andrey V. Panov  <panov@iacp.dvo.ru>

	* NEWS docs/gnuplot.doc src/term_api.h src/term.c src/gplt_x11.c
	src/set.c term/post.trm: New encoding koi8-r (Russian locale on Unices).
	SourceForge patch #853823.

2003-12-15  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/color.c (draw_color_smooth_box): Fixed position of color box
	to what it is in default view orientation, to make it stop
	rotating along with the plot.

2003-12-12  Ethan Merritt  <merritt@u.washington.edu>

	* docs/gnuplot.doc docs/gnuplot.texi term/post.trm term/x11.trm:
	Update the "New in Version 4.0" section of the docs, and change
	all the URLs for demos to point to the SourceForge web site rather
	than to Alex Woo's old web site at nasa.gov.

	* docs/gnuplot.doc docs/gnuplot.texi docs/titlepag.tex
	src/Makefile.am src/plot.c: Change references to mailing lists to

	gnuplot-info@lists.sourceforge.net
	gnuplot-bugs@lists.sourceforge.net
	gnuplot-beta@lists.sourceforge.net

	There are many more explicit references to dartmouth.edu in the
	source files and in the hard-wired Makefiles that I did not
	change.

	* demo/bivariat.dem: Fix key placement in final plot.

	* demo/webify.pl: New File. This is a perl script that converts a
	single gnuplot demo script into a web page with associated png
	images.  I used it to generate a new set of demo pages for version
	4 on gnuplot.sourceforge.net/demo/index.html

2003-12-05  Ethan Merritt  <merritt@u.washington.edu>

	* term/x11.trm: Leave current window unchanged when closing old
	window using the 'set term x11 <old> close' command.

2003-12-02  Ethan Merritt  <merritt@u.washington.edu>

	* term/svg.trm: Add conditional code to make svg output compatible
	with the Sodipodi svg viewer/editor. Sodipodi does not yet
	implement the full svg syntax, including the "currentColor"
	attribute. This change was checked for correctness using the Adobe
	svg viewer, which produces the same display given either the
	original or the simplified output.

	* term/svg.trm: Force a new graphics context whenever linewidth
	changes.

2003-12-01  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/tables.h (enum set_id): Renamed parser constant S_OUTPUT to
	SET_OUTPUT, in order to avoid collision with MacOS X 10.3 system
	headers.

	* src/tables.c (set_tbl): Likewise.

	* src/set.c (set_command): Likewise.

	* src/unset.c (unset_command): Likewise.

	* src/show.c (show_command): Likewise.

2003-12-01  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/command.c src/history.c docs/gnuplot.doc: New option
	"history quiet" to suppress enumeration of history entries (helps
	cut&paste).

2003-11-30  Ethan Merritt  <merritt@u.washington.edu>

	* term/post.trm src/term_api.h src/term.c: Move enhanced text mode
	parsing and processing from post.trm to the gnuplot core. This
	requires 3 new entries in TERM_TABLE for any terminal driver that
	wants to share the enhanced text code. The behaviour of the
	postscript terminal is unaffected by this change.
	
	* src/gplt_x11.c term/dumb.trm term/gd.trm term/pdf.trm
	term/x11.trm NEWS: Add enhanced text mode support to four
	additional drivers. The implementation in dumb.trm is intended as
	sample code for extending enhanced text mode support to other
	drivers.

2003-11-30  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/gnuplot.doc: Get documentation for 'palette gray' and
	'palette gamma' close together.

2003-11-30  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/command.c (test_palette_subcommand): Don't forget the replot
	command after 'test palette'.

	* src/setshow.c src/set.c: Global variable enable_reset_palette to
	enable/disable reset_palette(). Required by 'test palette'.

2003-11-28  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/os2/gclient.c: Fixed vertical and horizontal shifts
	associated to text angles.

2003-11-28  Petr Mikulik  <mikulik@physics.muni.cz>

	* tables.c: Moved definition of test_tbl[] out of #ifdef PM3D.

	* command.c (test_palette_subcommand): Reworked 'test palette' to
	use only one temporary file.

2003-11-25  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c term/x11.trm: Clean up code to remove compiler
	warnings.

	* src/parse.h src/unset.c: Export a prototype for
	cleanup_udvlist().

	* src/command.c: Include "getcolor.h" for rgb1_to_gray prototype.

2003-11-25  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/variable.c (PATHSEP_TO_NUL): Reindented.  Applied do {}
	while(0) wrapper.
	(PRINT_PATHLIST): Renamed from PRINT_LOADPATH.  Reindented.
	Applied do {} while (0) wrapper.  Made pointer variable local to
	the macro, initialize it from additional argument for clarity.
	(loadpath_handler, fontpath_handler): Removed static local
	'beenhere'.  Test directly for 'p != NULL' in ACTION_GET handler
	instead.

2003-11-25  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/command.c (test_palette_subcommand): Don't crash 'test
	palette' in read-only directory.

2003-11-24  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/xlib.h: Fixed typo (missing ` makes some of doc2xxx fail).

2003-11-24  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/gnuplot.doc src/gp_hist.h src/command.c src/history.c:
	Allow 'history "file"' be a pipe. New option 'history "file"
	append'.

2003-11-24  Daniel J Sebald  <daniel.sebald@ieee.org>

	* NEWS src/gplt_x11.c term/x11.trm: SourceForge patch #774822.
	Organized x11 terminal windows into a linked list. Removed the
	limit of max 16 enumerated terminal windows. New options 'set term
	x11 close' and 'set term x11 title "<title>"'.

2003-11-24  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS docs/gnuplot.doc src/command.h src/command.c src/tables.h
	src/tables.c src/term.c: New command 'test palette' for testing
	rgb profiles of the current palette. Command 'test' gets an
	optional argument of what to test: 'test terminal' (default) is
	what 'test' currently does.  Undocumented command 'testime'
	changed to 'test time'.

2003-11-21  Ethan Merritt  <merritt@u.washington.edu>

	* src/show.c: Remove unused variables to quiet compiler warnings.

	* src/parse.c src/unset.c: Add garbage collection of defunct
	user-defined variables. This plugs a small memory leak that would
	grow into a much larger one if/when we add string variables.

	* src/graphics.c: Break out creation of key entries into a
	separate subroutine, with related code cleanup. This is more
	preparation for support of multiple keys.

2003-11-20  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/win/wgraph.c (drawgraph): Fix names of struct elements
	changed on 2003-11-13.

2003-11-18  Ethan Merritt  <merritt@u.washington.edu>

	* src/specfun.c: Add parens to make DEC cc compiler happy.

2003-11-18  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/unset.c (unset_colorbox) (unset_pm3d): Removed extra
	c_token++.

2003-11-18  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/color.c (cbtick_callback): Fixed position of nomirrored
	horizontal color box tics.

2003-11-17  Ethan Merritt  <merritt@u.washington.edu>

	* term/xlib.trm src/term.h: Update xlib device to use the actual
	x11 driver routines, so the output will be identical.

2003-11-14  Ethan Merritt  <merritt@u.washington.edu>

	* term/post.trm: Fix bug in enhanced text overprint mode; vertical
	offset of overprinted text is now honored as specified in the
	documentation.

2003-11-13  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/history.c (write_history): Typo fixed.

	* src/command.c (history_command): Better error message for the
	"history" command not being available for GNU readline.

2003-11-13  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS src/show.c docs/gnuplot.doc: Options {float | int} for
	'show palette palette <n>', and let the output go to that of 'set
	print'.

	* src/command.h src/command.c: Let variables print_out and
	print_out_name be global instead of static.

2003-11-13  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/axis.h src/axis.c src/plot3d.c: Renamed set_pm3d_zminmax()
	to set_cbminmax().

2003-11-13  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/color.h src/color.c src/getcolor.h src/getcolor.c
	src/gplt_x11.c src/show.c src/win/wgraph.c term/metapost.trm
	term/pdf.trm term/svg.trm: New structure rgb255_color for uchar
	r,g,b.  Renamed color_from_gray() to rgb1_from_gray(). Renamed
	rgb_from_gray() to rgb255_from_gray(). New routine
	rgb255_from_rgb1().

2003-11-10  Ethan Merritt  <merritt@u.washington.edu>

	* src/color.c: Don't try to set color of non-supporting terminals.

2003-11-06  Ethan Merritt  <merritt@u.washington.edu>

	* configure.in, term/pdf.trm:  Test for and accommodate older
	versions of pdflib.

2003-11-01  Ethan Merritt  <merritt@u.washington.edu>

	* term/x11.trm: Do not use %lg to printf doubles. Some compilers
	complain because it is not strict ANSIC.

2003-10-31  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/x11.trm src/gplt_x11.c: Added  #ifdef PIPE_IPC  where missing
	(fixes compiling X11 terminal on OS/2).

2003-10-29  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* docs/gnuplot.doc, term/unixplot.trm: Fix misprints in gnuplot manual
	(#13).

2003-10-27  Ethan Merritt  <merritt@u.washington.edu>

	* demo/*.dem: Replace deprecated syntax in demos with current
	preferred syntax.

2003-10-23  Ethan Merritt  <merritt@u.washington.edu>

	* term/x11.trm: Add a soft lock on the mousing pipe so that input
	from stdin is delayed until completion of a query/response operation
	over the mousing pipe.  This fixes the problem of input characters
	being lost when stdin is fast (e.g. a script) and the X11 response
	is slow. It does *not* fix the problem with unbuffered input being
	lost, e.g. from awk scripts.
	
2003-10-22  Petr Mikulik  <mikulik@physics.muni.cz> 

	* src/set.c reset_palette(): Added missing reset of variable
	pm3d_last_set_palette_mode. Bugfix by Daniel J Sebald.

2003-10-21  Ethan Merritt  <merritt@u.washington.edu>

	* src/specfun.c: Fix reported bug #826811. The inverse_error_func()
	code to perform Newton-Raphson improvement was incorrectly nested
	so that it was only invoked in 1 of 3 range cases. Also empirical
	testing indicated that a 3rd cycle of Newton-Raphson was needed.

2003-10-21  Petr Mikulik  <mikulik@physics.muni.cz> 

	Changes allowing to save gnuplot session to a pipe, for example
	save "|cat >a.gp".

	* docs/gnuplot.doc: Documentation update.

        * src/command.c capture_filename_and_pfopen(): New routine, like
        CAPTURE_FILENAME_AND_FOPEN but with popen() in addition.

	* src/command.c save_command(): Reorganized.

        * save.c save_functions() save_variables() save_all() save_term():
	Reorganized.

2003-10-17  Petr Mikulik  <mikulik@physics.muni.cz> 

	* docs/old/README.os2: File removed. Information therein were already
	moved into appropriate places of gnuplot documentation long time ago.

2003-10-17  Petr Mikulik  <mikulik@physics.muni.cz> 

	* demo/animate.dem bivariat.dem borders.dem candlestics.dem discrete.dem
	fillcrvs.dem fillstyle.dem fontfile.dem fontfile_latex.dem hidden.dem
	mousevariables.dem multimsh.dem param.dem pm3d.dem pm3dcolors.dem
	pm3dgamma.dem poldat.dem random.dem scatter.dem steps.dem textcolor.dem
	textrotate.dem timedat.dem vector.dem: Added Id: tags and trailing reset
	command where missing.

2003-10-10  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/mouse.h src/gp_types.h: Moved enum of MODE_QUERY, MODE_PLOT, and
	MODE_SPLOT from mouse.h to gp_types.h to be available for non-mousing
	routines as well.

2003-10-10  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/graphics.c src/graph3d.c: Title of 'set key title' was not
	placed properly under simultaneous 'set key height'.

2003-10-08  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/tables.h src/tables.c: New routine lookup_table_nth.

2003-10-06  Ethan Merritt  <merritt@u.washington.edu>

	* axis.h: The recent (8 Sep) change to define NOOP as 0 caused
	gcc 3.2 -Wall to emit dozens of warning messages. Change this to
	#define NOOP ((void)0) instead.
	* interpol.c, plot2d.c: Remove extraneous redefinition of NOOP.

2003-10-06  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* configure.in (AC_PREREQ): Requirement raised to version 2.52 of
 	autoconf.
	(HAVE_DECL_SIGNGAM): New test, searches for declaration of signgam
 	variable in <math.h>.

	* src/specfun.c : General cleanup, adapting to gnuplot CodeStyle
 	conventions.  Changed function definitions to K&R style (keeping
 	ANSI prototypes).  Moved all prototypes to central place at head
 	of sourcefile.
	(signgam): Only activate own extern declaration if system provides
 	none --- might cause conflicts on strange systems.  This needs the
 	new autoconf test for HAVE_DECL_SIGNGAM.
	(ermsg): Message array marked const, moved into only routine using
 	it: mtherr().
	(polevl, p1evl): Marked argument coef and local pointer p const.
	(A, B, C, LS2PI, MAXLGM, LOGPI): Marked const; moved into the only
 	function using them: lngamma().
	(f_erf, f_erfc): Sanitized handling of local variable fsign.
	(f_erfc): Fix check for error-return from igamma().
	(f_gamma): Replace magic number 88.0 by negative of macro MINEXP.
	(pn1, pn2, pn3, pn4, pn5, pn6): Moved into single function using
 	them: igamma();
	(igamma): Remove spurious check of argument against MINEXP ---
 	gp_exp() already does that, if necessary.  This should fix SF bug
 	#806455.
	(Xm1, Xm2, Xa2, Xa2): Marked const; moved into only function using
 	them: ranf().
	(P0, Q0, P1, Q1, P2, Q2): Marked const; moved into only function
 	using them: inverse_normal_func().
	(UTHRESH, SQRTH, ndtr): Unused --- removed.
	(P, Q, R, S): Marked const, moved into only function using them:
 	erfc().
	(erfc): Only compile this if !defined(HAVE_ERFC).
	(T, U): Marked const, moved into only function using them: erf().
	(erf): Only compile this if !defined(HAVE_ERF).
	(inverse_error_func): Marked local parameter arrays a, b, c, d
 	static and const.

2003-09-12  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Part II of portability glitches reported by Scott Marovich from HP
 	labs:
	
	* term/x11.trm (X11_set_default_font): Made static to match
 	declaration.
	
	* term/png.trm (png_default_write_data) [PNG_NO_STDIO] : New
 	callback function to be used if libpng was built with the
 	PNG_NO_STDIO option.
	(PNG_text) [PNG_NO_STDIO]: Use it instead of png_init_io.

	* configure.in (--with-png): Test for png_create_write_struct
 	instead of png_init_io, since the latter can be removed from
 	libpng at build time.
	(--with-pdf): Remove spurious comma in test for libpdf and
 	pdflib.h precence.

2003-09-11  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/term.c (test_term): Fixed incomplete if statement.

2003-09-08  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Portability glitches reported by Scott Marovich from HP labs:

	* src/pm3d.h (PM3D_WHICH_CORNES2COLOR): Fix comma placement in
 	enumeration.

	* src/getcolor.c (color_components_from_gray): Remove trailing
 	semicolon after definition.

	* src/axis.h (AXIS_INDEX): Fix comma placement in enumeration.
	(NOOP): #define as 0 instead of /* */, to work around
 	preprocessors that forbid empty macro arguments.

	* src/gplt_x11.c (stipple_halftone_bits, stipple_pattern_bits):
 	Changed from unsigned char to straight char, to silence a compiler
 	warning.

2003-08-29 Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* configure.in (--with-pdf): Moved check for pdflib.h so it only
 	gets done if -lpdf itself was found.

	* src/beos/Makefile: Removed lots of spurious <TAB> characters.

2003-08-22  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* docs/gnuplot.doc, term/fig.trm, term/gd.trm, term/post.trm,
	term/x11.trm: Fix misprints in gnuplot manual (#12).

2003-08-20  Ethan Merritt  <merritt@u.washington.edu>

	* src/save.c src/show.c: Fix incomplete/incorrect description of point
	properties from 'set label' commands.

	* src/set.c docs/gnuplot.doc: Remove order-dependence of options to
	'set [xyz]label' command. Deprecate omission of 'font' keyword.

2003-08-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/parse.c (push_vars): Changed initialization to TRUE, as it
 	was before yesterday's patch.  Fixes SF bug #790489.

2003-08-17  Ethan Merritt  <merritt@u.washington.edu>

	* src/eval.h src/eval.c src/parse.c: There is no need to have
 	push_vars a global exported from eval.*; move it to parse.c, the
 	only user.

2003-08-16  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>
	
	* src/specfun.c [!GAMMA] (signgam): Replace explicit variable
 	definition by macro to map from sgngam in fall-back implementation
 	to default name.  Fixes gamma(x)==0 bug on Cygwin/MinGW32 builds.

2003-08-12  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c: Apply linewidth changes directly to pm3d mode (fixes
	bug that linewidths in pm3d were one plot late in being applied).

2003-08-08  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* term/aquaterm.trm: Updated from aquaterm cvs bugfix branch.
	Thanks to Per Persson for the note.

2003-08-05  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* Tag and release 3.8j.0 snapshot.

2003-08-05  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* demo/Makefile.am.in: Add equipo2.dat, field2xy.dat to CLEANFILES.

2003-08-05  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* docs/gnuplot.doc: Fix misprints in gnuplot manual (#11).

2003-08-04  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c term/x11.trm docs/gnuplot.doc:  Honor explicit request
	for "bold" or "medium" font weight when parsing X11 font requests.

2003-07-31  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c:  Fix incorrect bracketing of switch statement entries
	introduced way back in Dec 2000. This fixes the "x11 clipboard" bug.

2003-07-27  Ethan Merritt  <merritt@u.washington.edu>

	* docs/gnuplot.doc docs/titlepag.tex: This is a first pass at updating
	the "What is New" section to reflect changes since version 3.7. I also
	slightly re-arranged the sections on mousing, and added my name to the
	list of contributers.

2003-07-27  Ethan Merritt  <merritt@u.washington.edu>

	* src/command.c src/mouse.c docs/gnuplot.doc: Report key modifiers
	active at the time of a mouse click in variables MOUSE_SHIFT,
	MOUSE_ALT, and MOUSE_CTRL.

2003-07-23  Ethan Merritt  <merritt@u.washington.edu>

	* configure.in: Rename the configuration option for Jaime Reed's
	'defined(var)' code, and enable it by default.  The option is now
	./configure --disable-defined-var

	* show.c: Move listing of undefined variables to an FPRINTF.

2003-07-22  Ethan Merritt  <merritt@u.washington.edu>

	* src/command.c src/command.h src/mouse.c:
	Add a new user command 'pause mouse {"text"}'.  On mouse-capable
	terminals the pause will terminate on either a mouse click or on
	a <cr>; for all other terminals it is treated as 'pause -1'.

	* src/parse.c src/parse.h: Add a new function get_udv(key) that can
	search for user-defined variables even if the key is not a token in
	the current command line.

	* src/mouse.c src/command.c: When mousing is active, each mouse click 
	in the current plot window will update the current value of user-defined
	variables MOUSE_BUTTON MOUSE_X MOUSE_Y MOUSE_X2 MOUSE_Y2. In combination
	with Jaime Reed's patch below, this allows gnuplot scripts to test for
	the presence and result of mouse input.

	* src/gplt_x11.c term/x11.trm: Continue processing mouse activity for
	all displayed X11 windows.  This is necessarily done in gnuplot_x11,
	since gnuplot discards the old scaling information each time it starts
	a new plot. The mouse position is updated in the window itself.
	There is dummy code in gplt_x11.c that logs mouse clicks to stderr, but
	ideally it should be fed to some higher-level process (e.g. Octave).

	* docs/gnuplot.doc demo/mousevariables.dem: Document new mousing
	behaviour and provide a sample script that uses it.

2003-07-22  Jaime Reed <jaime2003@users.sourceforge.net>

	* src/parse.c src/eval.h src/eval.c src/standard.c src/standard.h
	src/internal.c src/internal.h configure.in:  Create a new builtin
	function "defined(<uservar>)" that returns 1 if the user variable
	is defined and returns 0 if undefined. This was patch #714750 on
	SourceForge.  Select at build time by ./configure --enable-isvar

2003-07-15  Ethan Merritt  <merritt@u.washington.edu>

	* src/gp_types.h src/graphics.c src/plot2d.c: Create a new flag
	PLOT_STYLE_HAS_BOXES and use this to trigger filled-box processing
	rather than testing individually for each plot style that uses it.

	* src/mouse.c: #include "util3d.h" to get prototype for map3d_xy().

2003-07-10  Ethan Merritt  <merritt@u.washington.edu>

	* term/x11.trm: Gnuplot disables mousing if it thinks the 
	controlling terminal is not interactive. In this case X11_graphics()
	must not attempt to wait for a mouse event during initialization
	[Fixes reported bug that first character of input line can be lost].

2003-07-07  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c: Detect request for illegal window number and
	treat it as window number 0.

	* term/x11.trm: Detect missing font name during "set term x11".

	* src/command.c: Add missing line from what should have been a
	patch too trivial for me to mess up (do_string).

2003-07-07  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/command.c (do_string_replot): Minor simplification: use
 	gp_strdup() to duplicate current input_line string.  Add some
	blanks as per CodeStyle document.
	(do_string): Likewise.

2003-07-04  Ethan Merritt  <merritt@u.washington.edu>

	* src/command.c: Rewrite do_string() and do_string_replot() so
 	that no memory corruption occurs if extend_input_line() triggers a
 	realloc(<xxx>,input_line) during processing.

	* term/x11.trm: Font requests to a remote X-server are very slow;
 	track font used for most recent text placement and only send a
 	font request if the current text font is different from the
 	previous one.

	* src/gplt_x11.c: Collect sequential vector draws into a single
 	polyline before sending it to the X-server. This makes wide lines
 	smoother, and gives a small speed improvement for remote displays.

	* src/graphics.c: Replace problematic adjustment of key placement
 	below plot with a better one.

2003-07-02  Ethan Merritt  <merritt@u.washington.edu>

	* src/mouse.c: DU4.0 cc compiler does not automatically promote
 	argument of sqrt to (double), so change it to double explicitly.

	* demos/arrowstyle.dem, demos/vector.dem: Show more of what the
 	`plot with vectors <arrowstyle>` option can do.

2003-07-02  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/pm3d.c (pm3d_reset): Forgotten change of the default value
 	from 'set pm3d clip1in' to 'set pm3d clip4in' in the patch from
 	2002-10-09.

2003-07-02  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/command.c (do_string_replot): Don't allocate so much of the
 	temporary buffer.

2003-07-01  Ethan Merritt  <merritt@u.washington.edu>

	* src/graphics.c: Make sample arrow in plot key match the arrow
 	style used by 'plot with vectors'.

2003-06-30  Ethan Merritt  <merritt@u.washington.edu>

	* src/misc.h src/misc.c src/plot2d.c src/set.c docs/gnuplot.doc: 
	Vector plots are drawn using the linetype in a stored arrowstyle 
	structure. Make sure this defaults to the linetype for the current
	plot #, and that this and the overall plot linetype always agree.

2003-06-27  Ethan Merritt  <merritt@u.washington.edu>

	* src/set.c: Fix unexpected behaviour that 'set grid nox noy'
	turned the x and y grids ON rather than off.

2003-06-26  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* term/dxf.trm (DXF_HTIC, DXF_VTIC):  Fixed definitions so 'set
	size ratio' can work.

2003-06-25  Ethan Merritt  <merritt@u.washington.edu>

	* src/term_api.h src/command.c term/x11.trm: Define a flag
	TERM_INIT_ON_REPLOT by which a terminal driver can request that
	term->init() be called at the start of a replot command.

	* src/gplt_x11.c src/mouse.c: Send the current true size of the
	x11 display window back from gnuplot_x11 to x11.trm during
	term->init(). Use this information to update the aspect ratio.

2003-06-21  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c: gnuplot_x11<->x11.trm font info exchange is now
	working.

2003-06-20  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c:
	It turns out that yesterday's patch breaks the "pause -1" command
	(it always returns immediately).  I have temporarily disabled the
	new code while I track down the problem.  The offending line is now
	protected by #ifdef X11_FONT_UPDATE.

	* term/x11.trm:
	Add an interlock so that the gnuplot_x11<->x11.trm font info exchange
	is only performed once per splot, rather than every time the view is
	changed using the mouse.

2003-06-19  Ethan Merritt  <merritt@u.washington.edu>

	* src/gplt_x11.c src/graphics.c src/mouse.c src/mousecmn.h term/x11.trm
	Use existing mouse communication pipe to send X11 font characteristics 
	back from gnuplot_x11 to x11.trm. This allows gnuplot to lay out the 
	plot with v_char and h_char sizes that are correct for the current 
	default X11 font. This patch slightly changes the timing of initial
	operations over the pipe, and adds a FFLUSH(), so there is a remote 
	possibility that it also fixes a reported problem in which gnuplot_x11
	eats CPU cycles while supposedly idle. This patch should have no effect
	if gnuplot is configured with --disable-mouse.

	* term/pslatex.trm: Escape % to %% inside printf() statement.

2003-06-18  Ethan Merritt  <merritt@u.washington.edu>

	* term/gd.h: Fix FPRINTF typo.

2003-06-16  Petr Mikulik  <mikulik@physics.muni.cz>

	* command.c do_string_replot(): Dynamically allocate temporary input
	line buffer instead of using a fix-size one. Fixes crash when replotting
	a long plot command by mouse/hotkey.

2003-06-15  Ethan Merritt  <merritt@u.washington.edu>

	* src/graphics.c: Center key title over entire key box rather than
	cramming it into the first column only.

2003-06-14  Ethan Merritt  <merritt@u.washington.edu>

	* term/epslatex.trm: Clean up file name handling; now it is OK to give
	either .eps or .tex in 'set output', or no file extension at all.

2003-06-13  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* docs/gnuplot.doc, term/epslatex.trm: Fix misprints in gnuplot manual.

2003-06-11  Ethan Merritt  <merritt@u.washington.edu>

	* term/epslatex.trm term/pslatex.trm: Add text rotation.

	* term/epslatex.trm: Add missing PostScript macros used by 
	t->filled_polygon.

	* src/term.c: Fix size of test polygon relative to plot.

2003-06-09  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* INSTALL, configure.in: Add note about GNU readline bug.
	
	* docs/Makefile.in, src/makefile.all, src/term.h, term/aquaterm.trm:
	Add support for AquaTerm, a new MacOS X graphics terminal.

	* src/Makefile.am: Fix for bug #738816 "configure --without-x not
	effective".

	* src/readline.c: Remove gnuplot SIGWINCH handler, see note about
	GNU readline bug.

2003-06-04  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/show.c (show_palette_fit2rgbformulae): Take care of color models.

2003-06-03  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/show.c (show_palette_rgbformulae show_palette_palette
	show_palette_colornames): Fixed indentation.

2003-06-03  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS src/show.c docs/gnuplot.doc: New command 'show palette
	fit2rgbformulae'.

2003-05-23  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/gplt_x11.c (main) [!DEBUG]: Redirect stderr to /dev/null on
 	entry to -persist mode event loop.  Avoids hanging emacs if you
 	run "gnuplot -persist" via shell-command.  In DEBUG mode, leave it
 	alone.

2003-05-19  Ethan Merritt  <merritt@u.washington.edu>

	* term/svg.trm: Make pattern fill sequence consistent with other
 	terminal types. Fix off-by-one y coordinate error in box fill
 	code.

2003-05-19  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/show.c (show_palette_colornames): Fix a C++-ism (variable
 	declarations not at the beginning of a block).

2003-05-17  James R. Van Zandt  <jrv@debian.org>

	* term/README: spelling and grammar fixes

2003-05-17  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/svg.trm: Support filled polygons with more than 4 corners.

2003-05-17  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/show.c show_palette_colornames(): Command 'show palette
	colornames': print color names and their rgb values (was printing
	only names).

2003-05-16  Ethan Merritt  <merritt@u.washington.edu>

	* src/gadgets.h src/graph3d.c src/graphics.c src/save.c src/set.c
	src/show.c src/tables.c src/tables.h src/unset.c docs/gnuplot.doc:
	Add new command options 'set key {on|off|default}'.
	Using 'set key' to restore default values is deprecated.

2003-05-16  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.mgw config/makefile.cyg: New configuration define
	GNUSORT.

2003-05-13  Ethan Merritt  <merritt@u.washington.edu>

	* src/plot2d.c docs/gnuplot.doc: Apply current fill style to boxes 
	drawn for 'plot with boxxyerror'.

2003-05-10  Ethan Merritt  <merritt@u.washington.edu>

	* term/x11.trm: Expand documentation of font handling.
	* src/readline.c: Allow <tab> characters in input stream.

2003-05-09  Ethan Merritt  <merritt@u.washington.edu>

	* term/cgm.trm: Add missing prototype for CGM_fillbox().
	* src/term.c: Work around Microsoft compiler inadequacy.
	* src/datafile.c: Trap missing filename in df_open().

2003-05-06  James R. Van Zandt  <jrv@vanzandt.mv.com>

	* term/cgm.trm (CGM_fillbox): Implement pattern filled boxes,
	conditioned on USE_ULIG_FILLEDBOXES.

2003-05-06  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/term.c (test_term): Improvements in the 'test' command: Some of
	the text labels are in colors; added test for text at +-45 deg; added
	test for mouse and for pm3d.

2003-05-06  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/mouse.c (recalc_ruler_pos): Take care of ruler in 'set view map'
	splot.

2003-05-04  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/datafile.c: Fixed #define is_comment(c): strchr(s,c) returns
	!NULL for c=0.

2003-05-03  Ethan Merritt  <merritt@u.washington.edu>

	* term/mif.trm: Implement support for filled boxes, pattern fill
	and for PM3D filled polygons.

2003-05-01  Ethan Merritt  <merritt@u.washington.edu>

	* term/pdf.trm: Remove limit of 4 vertices in fill_polygon().

2003-04-30  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/gnuplot.doc: Say that the either of `set datafile commentschars`
	characters must be the first non-blank blank character on the line.

2003-04-29  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS docs/gnuplot.doc src/datafile.c src/datafile.h src/save.c
	src/set.c src/show.c src/syscfg.h src/unset.c: New option 'set datafile
	commentschars'.

2003-04-24  Ethan Merritt  <merritt@u.washington.edu>

	* term/post.trm: The postscript terminal driver now implements
	pattern-fill via a (Level 1) PostScript subroutine rather than via
	a loop in the driver-level C code. Thanks to Dick Crawford.

	* src/bitmap.c src/gplt_x11.c src/win/wgraph.c 
	term/emf.trm term/gd.trm term/pdf.trm:
	Bring all terminal types that support pattern-fill into agreement
	about the order of patterns. The patterns have been chosen for
	maximum contrast in mono plots, and to favor symmetric patterns
	over diagonal lines that are hard to describe in figure captions.

	Pattern fill support is now uniform for the following terminals
		epslatex
		gd (png jpeg)
    		bitmap (pbm epson hp500c hpljii hppj)
    		pdf
		postscript
		pslatex
		windows
		x11
	Not implemented but probably should be
		aifm
		eepic
		emf

2003-04-24  Ethan Merritt  <merritt@u.washington.edu>

	* src/win/wgraph.c: Tweak previous correction to saved pen color
	so that it applies cleanly to box fill as well.

2003-04-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/win/wgraph.c (drawgraph): Fix signedness bug exposed by
	saving the "test" page to the clipboard.  Shift value of local
	variable "pen" by 2 to keep it non-negative.

	* config/makefile.cyg (CFLAGS): Add missing "endif".
	(veryclean): Remove pgnuplot.exe, too.

2003-04-18  Daniel J Sebald  <daniel.sebald@ieee.org>

	* src/gplt_x11.c (process_event): Patch "[ 707940 ] bug fix for
	graph height underflow 690018". Fixes graph size when mouse is
	on/off. The fix is simply to check if vchar > plot->height, and if
	so set plot->gheight to zero otherwise plot->gheight =
	plot->height - vchar.

2003-04-18  Harald Harders  <h.harders@tu-bs.de>

	* docs/psdoc/ps_fontfile_doc.tex: Patch "[ 696421 ] Improved
	ps_fontfile_doc". Some text is modified, the symbol table now
	includes the octal and decimal numbers of the characters.

2003-04-18  Petr Mikulik  <mikulik@physics.muni.cz>

	* gnuplot.doc unset.c(reset_command): Remove "unset_loadpath()"
	from reset command. After discussion on gnuplot-beta list, the
	"reset" command should reset only graphics settings, while it
	should let unchanged non-graphics settings (like set term, out,
	loadpath and fontpath).

2003-04-13  Ethan Merritt  <merritt@u.washington.edu>

	* src/term.c src/graphics.c: Correct a syntax error in test for
	terminal support of filled boxes.  This fixes reported crashes
	under MSWin.

	* src/gadgets.c src/mouse.c: Fix the same syntax error in other
	files also, although no crashes have been reported for these.

2003-04-13  Ethan Merritt  <merritt@u.washington.edu>

	* term/gd.trm: Document that libgd will handle both TrueType and
	Adobe Type 1 fonts.

	* src/unset.c: Set tic label rotation to 0 on unset or reset.

2003-04-04  Ethan Merritt  <merritt@u.washington.edu>

	* term/pslatex.trm term/epslatex.trm: Add filled box support.

	* term/eepic.trm: Fix broken parsing of terminal options.

	PSTRICKS_previous_palette.

2003-04-04  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* config/makefile.nt (winmain.obj): Don't repeat HELPFILE
	definition --- already part of CFLAGS.

2003-04-04  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.os2: Support for IPFC 2.1. Use temporary script file
	when creating allterm.h.

2003-04-03  Ethan Merritt  <merritt@u.washington.edu>

	* src/term.c: Only test fill patterns on terminals that support it.

2003-04-01  Ethan Merritt  <merritt@u.washington.edu>

2003-03-31  Ethan Merritt  <merritt@u.washington.edu>

	* src/bitmap.c src/gplt_x11.c term/gd.trm term/pdf.trm:
	Add a cross-hatch fill pattern. The change to bitmap.c affects the
	epson, hpxx, and pbm terminal types.

2003-03-31  Ethan Merritt  <merritt@u.washington.edu>

	* src/bitmap.c term/pdf.trm: Revise the order of colors slightly
	to maximize contrast between successive plots (affects gd.trm also).

	* src/term.c: Add linewidth and fill patterns to terminal test.

2003-03-26  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/save.c (save_set_all): Don't compare an enum label to a
 	pointer; not even if the enum is zero.  Found by John Bollinger on
 	MS VC++.

	* src/show.c (show_key): Likewise.

2003-03-26  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS term/gnugraph.trm term/openstep.trm: 
	Terminal provided by openstep is called "openstep", not "next".
	Terminal provided by gnugraph is called "gnugraph", not "unixplot".

2003-03-22  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/gnuplot.doc: Pronounce looking at demo/pm3d.dem.

	* demo/pm3d.dem: In demo of corners2color, transpose positions of
	'c2' and 'c3'.

2003-03-22  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/post.trm(PS_filled_polygon): Don't call PS_FLUSH_PATH but reset
	ps_path_count instead (flush is automatic). Fixes broken pm3d map
	layout (required by pm3dConvert*.awk scripts) due to "stroke\n" in
	PS_FLUSH_PATH.

	* demo/pm3d.dem: Replace "set view 180,..." by "set pm3d map".

2003-03-21  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/x11.trm: Allow to use both the default '"gnuplot_x11.exe"' and
	optional 'GNUPLOT_X11 ".exe"' for initializing X11_default_command[]
	under OS/2 and Windows.

2003-03-21  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* term/gd.trm term/gif.trm: Added #undef gdfont after it is not used
	any longer.

2003-03-20  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/eval.c (gp_exp): Make this a function in all cases.  If
 	MINEXP wasn't set, use special version that removes ERANGE caused
 	by large negative arguments to exp().

	* src/eval.h (gp_exp): Don't #define gp_exp() if no MINEXP set.

	* src/specfun.c (inverse_error_func): Call sanitized gp_exp()
 	instead of plain exp().

2003-03-18  Ethan Merritt  <merritt@u.washington.edu>

	* term/gd.trm: Default to medium size font (7x13) as claimed
	by the documentation and by the output of show term; fixes
	bug 696179. If the user provides new colors in 'set term', then
	overwrite any previously specified colors (bug 702382).

2003-03-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

 	dependency.
	
2003-03-17  Leo Brewin <leo.brewin@sci.monash.edu.au>

	* term/pdf.trm: Tell pdflib to use its built-in font metrics for
 	Symbol and ZapfDingbats fonts, since not all hosts have these.

2003-03-14  Petr Mikulik  <mikulik@physics.muni.cz>

	* demo/pm3d.dem: Improved demo for corners2color.

	* docs/gnuplot.doc: Proofreading pm3d section.

2003-03-13  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS src/pm3d.h src/pm3d.c src/tables.h src/tables.c src/save.c
 	src/set.c src/show.c demo/pm3d.dem docs/gnuplot.doc: New pm3d
 	option 'corners2color'.

2003-03-13  Ethan Merritt  <merritt@u.washington.edu>

	* set.c: Consolidate set_{blrt}margin into a single routine, break
 	out text_label creation and label option parsing into separate
 	routines so that they can be called separately, general code
 	cleanup.

	* unset.c: Consolidate unset_{blrt}margin into a single routine.

2003-03-07  Ethan Merritt  <merritt@u.washington.edu>

	* graphics.c: Filled boxes can obscure the x-axis (see for example
 	fillstyle.dem); fix this by retracing the axes at the end of
 	plotting.

2003-03-06  Wilhelm Braunschober  <Wilhelm.Braunschober@t-online.de>

	* term/svg.trm (SVG_fixed_size): New configuration variable.

	(SVG_options): Handle new option 'size {fixed|dynamic}'.  Fix font
 	name input to write to FontNameCur, not FontNameDef.
	(SVG_init): Use FontNameCur instead of FontNameDef.  Implement
 	encoding ISO-8859-1 and dynamic size option.

2003-03-04  Petr Mikulik  <mikulik@physics.muni.cz>

	* pm3d/contrib/colorpts-demo.gp: Removed explicit 'set term'.

2003-03-03  Ethan Merritt  <merritt@u.washington.edu>
	
	* demo/candlesticks.dem docs/gnuplot.doc src/graphics.c:
	Allow 'set boxwidth' to control the box part of candlesticks.
	If no boxwidth is set, then default to previous behavior.

2003-03-02  Ethan Merritt  <merritt@u.washington.edu>
	
	* src/graphics.c: The calculation of plot boundary size is a tangle of
	interdependent size estimates. While not addressing the underlying
	problem, this patch at least makes the key size match the final plot
	size.

2003-02-26  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* demo/fillbox.dem: Update to changed syntax of filled boxplots

2003-02-21  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* term/post.trm (PS_vector): Fix bug introduced by the changes
 	against postscript error accumulation.  Would create paths with a
 	move as the first command.

2003-02-19  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.mgw config/makefile.cyg config/makefile.os2:
 	Somebody has redefined HAVE_TTF to HAVE_GD_TTF without making
 	appropriate changes here!

2003-02-19  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/graphics.c (histeps_compare): There was a wrong comparison
 	returned by this qsort-called routine, which caused 'plot with
 	histeps' buggy.

2003-02-19  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* ChangeLog: Modified an old log entry that contained an actual
 	RCS date tag, which caused it to be updated every time ChangeLog
 	was checked in.
	
2003-02-19  John Bollinger <bbands@yahoo.com>

	* config/makefile.nt (default): Build pgnuplot.exe, too.

2003-02-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* term/post.trm: Re-indented in several places.
	(PS_vector): Implemented workaround for apparent ghostscript bug
 	causing accumulated precision loss in long sequences of relative
 	moves / lines.

	* CodeStyle: Got rid of lots of // style comments all over the
 	source code, as well as some that look suspiciously like them.
	
2003-02-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	The patch for "fit error variables", SF patch #677470, contributed

2003-02-15  Ethan Merritt  <merritt@u.washington.edu>

	* src/gadgets.h src/gadgets.c src/set.c src/save.c src/unset.c 
	src/graph3d.c src/graphics.c src/plot2d.c src/plot3d.c:
	Move all globals related to the plot legend (key) into a single
	structure. This yields cleaner code, and should eventually allow 
	multiple legends per plot.

2003-02-14  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* docs/gnuplot.doc (fit): Mention that 'thru' doesn't apply to

	font height and width each time a new TTF font is set in PNG_set_font().

2003-02-06  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* lisp/configure.in: Determining emacs version was broken for GNU Emacs.

2003-02-04  Ethan Merritt  <merritt@u.washington.edu>

	* src/set.c: Trap syntax error 
	* docs/gnuplot.doc Fix indentation, and add a section for `unset`.

2003-02-04  Ethan Merritt  <merritt@u.washington.edu>

	* NEWS docs/gnuplot.doc src/datafile.c src/datafile.h src/save.c 
	src/set.c src/show.c src/unset.c: 
	Add new command `set datafile separator { whitespace | "<char>"}`.
	This allows plotting from tab- or comma- separated data files.

2003-02-04  Ethan Merritt  <merritt@u.washington.edu>

	* term/emf.trm: Revise handling of text color and point style to
 	match other terminal types. NB: Justification of rotated text is

2003-01-27  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Fix some bugs in handling of reversed axes.
	
	* src/axis.h (struct AXIS): Renamed element "reverse_range" to
 	"range_is_reverted", which explains its usage more clearly.  All
 	usages of this element renamed, throughout the source.
	(AXIS_INIT3D, CHECK_REVERSE): Mask "autoscale" by AUTOSCALE_BOTH
 	before comparison, to avoid disruption by AUTOSCALE_FIX{MIN|MAX}
 	bits stored in there, too.

	* src/stdfn.h (cliptorange): New macro to simplify clipping values
 	to potentially reversed ranges.

	* src/axis.c (setup_tics): Introduced local "this" pointer into
 	axis_array.  Locals fixmin,fixmax renamed to autoextend_{min|max},

	* src/axis.h: Removed patch 2003-01-25 about of the changed
 	definition of AUTOSCALE_FIXMIN and AUTOSCALE_FIXMAX. The bug of
 	reversed y-axis, "set autoscale fix" and mouse zooming seems to be
 	more tricky.

2003-01-25  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/show.c: Fix typo HAVE_GD_TTY to HAVE_GD_TTF.

2003-01-25  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/axis.h: Change the definition of AUTOSCALE_FIXMIN from 1<<2
 	to AUTOSCALE_MIN | 1<<2. Similarly for AUTOSCALE_FIXMAX. Fixes a
 	bug of wrong z- and cb-ranges during mouse zooming of a pm3d
 	splot.

2003-01-24  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

2003-01-24  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/plot.c src/set.c docs/gnuplot.doc: Let the default terminal
 	or that (re)set from gnuplot's ini file pushed automatically
 	during gnuplot's startup. Consequently, 'set term pop' will be
 	always defined to be the default terminal on the given platform,
 	unless changed explicitly by 'set term push'.

	* src/misc.h src/misc.c: New routines push_terminal() and
 	pop_terminal().

2003-01-23  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	New Windows menu contributed by John Bollinger <bbands@yahoo.com>:
	
	* src/win/wgnuplot.mnu: The new menu definition itself.

	* src/win/wmenu.c (MACROLEN): Increased to 10000 to accomodate
 	larger menu.

	* src/win/wresourc.h (NUMMENU): Increased to 512 to accomodate
 	larger menu.

	* src/win/wgnuplib.h (WGNUPLOTVERSION): Bumped up because NUMMENU
 	change makes DLL API incompatible.

2003-01-22  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* FAQ, src/syscfg.h: Update FAQ location.

	* configure.in: Fix faulty regexp in sed command and vgagl reporting.

2003-01-22  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/README src/color.c term/post.trm: Changed "continous" to
	"continuous".

	* term/fig.trm: Fix text centering for nonzero text angle.

2003-01-13  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/plot3d.c (get_3ddata): Move dgrid3d call outside if-else
 	block to have it work with binary and matrix data, too.

2003-01-09  Ethan Merritt  <merritt@u.washington.edu>

 	like in docs/Makefile.in.

2003-01-08  Petr Mikulik  <mikulik@physics.muni.cz>

	* doc/gnuplot.doc: Remove duplication of hypertext labels "set

 	user to specify textcolor and font for axis tick labels.

2002-12-27  Ethan Merritt  <merritt@u.washington.edu>

	* src/set.c: Check for legal value of linetype in
 	parse_colorspec().

	* src/unset.c: Invoke 'unset_missing' during a reset. Avoid
 	calling int_error() from inside a reset, because this prevents it
 	from restoring the interactive context on exit.

2002-12-18  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* configure.in: Completely rewritten and simplified checks for
 	png, gd, and the required support libraries. Other minor cleanups.

	* config/config.amg, config/makefile.cyg, config/makefile.mgw,
 	config/makefile.os2, src/show.c, src/term.h, term/gd.trm,

 	gd/png/jpeg checks.

2002-12-17  Ethan Merritt  <merritt@u.washington.edu>

 	linewidth.

	* term/gd.trm: Check for valid linetype (Mike Kay
 	<kay@fsl.noaa.gov>).

 	Pieter-Tjerk de Boer <ptdeboer@cs.utwente.nl>.

	* src/fit.c (fit_command): Replace EOF by DF_EOF in return value
 	check of df_readline call.

2002-12-17  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* docs/Makefile.in: Adjust DEFAULT_INCLUDES and INCLUDES. Remove
	jpeg.trm from CORETERM. New generated file term.h, used instead of
	../src/term.h, and adjust dependencies accordingly. Better rule to
	generated allterm.h.

	* term/epslatex.trm: Fix typos in help section (was labeled as post
	instead of epslatex).

	* term/pdf.trm, term/svg.trm: Fix indentation of term help section.

	* term/png.trm: Rename "png (OLD)" to "png_old" to allow for
	alphabetical sorting of term help entries.

	* term/vgagl.trm: Remove spaces-only line from end of term help.

2002-12-13  Lars Hecking  <lhecking@nmrc.ucc.ie>

	docs/termdoc.c, docs/xref.c: Fix compiler warnings, ansify.

	* docs/gnuplot.doc: Update copyright date.

	* docs/psdoc/Makefile: Fix clean target.

	* docs/psdoc/ps_fontfile_doc.tex: Harald Harders' patch to improve
	ps fontfile documentation.

2002-12-13  Shigeharu Takeno  <shige@iee.niit.ac.jp>

	* term/cgm.trm, term/eepic.trm, term/hpgl.trm: Another installment
	of documentation fixes.

2002-12-15  Ethan Merritt  <merritt@u.washington.edu>

	* configure.in: If the TTF support routine in libgd is found under its
	old name gdImageStringTTF then force gd.trm to use old name instead of 
	the newer gdImageStringFT.  This addresses support request 652960, and
	is necessary for compatibility with libgd < 1.8.4. 

2002-12-15  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.mgw config/makefile.cyg: Compile doc2tex with
	allterm.h so that gnuplot.tex documents all terminal drivers, not only
	those currently used.

	* post.trm(START_HELP): Added label 'postscript fontfile'.

2002-12-13  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/titlepag.ms docs/titlepag.tex docs/gnuplot.doc: Added my name to
	the authors section.

2002-12-13  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/titlepag.tex: Added fancy headings. Better procedure to read
	gnuplot version from file VERSION.

2002-12-13  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* FAQ: Regenerated and updated.

	* docs/doc2texi.el: Add all terminal drivers to d2t-terminal-list.

	* src/datafile.c demo/pm3d.dem: Binary datafiles now accept 'using'
	with 4 parameters for independent z and color values of splotting
	'with pm3d' and 'with lines|points palette'.

2002-07-02  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS src/plot3d.c docs/gnuplot.doc: Support plotting surfaces with
	color lines or points with color according to explicitly given 4th
	column, e.g. "splot ... using 1:2:3:4 with [line|point] palette".

	* src/plot3d.c: The color for the color value of lines, colors, pm3d
	vertices is taken from the 3rd data column unless the 4th column is 
	explicitly stated by "using"; thus, the same splot is obtained
	regardless whether the input data file has 3 or 4 columns.

	* src/axis.h: Added condition "|| PM3D_IMPLICIT == pm3d.implicit" into
	macro NEED_PALETTE(plot).

	* src/datafile.h src/datafile.c: Routine df_3dmatrix(): don't use
	macro NEED_PALETTE(plot), but take parameter input_palette() --- this
	avoids #include "pm3d.h" in datafile.c.

2002-06-16  James R. Van Zandt  <jrv@debian.org>

	* term/cgm.trm: silently drop any labels outside the CGM plot
	window.  (This should eliminate the errors like "gnuplot:
	../term/cgm.trm:1150: CGM_write_int: Assertion `value <= 32767'
	failed.  Aborted (core dumped)".	

2002-06-11  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/fig.trm: Support for 'set palette maxcolors <n>'. Treat properly
	the case of color palette and monochrome fig file.

2002-06-10  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/pdf.trm term/svg.trm: Support for 'set palette maxcolors <n>'.

	* term/win.trm: Better document the meaning of 256 levels in
	WIN_make_palette(). Remove the previous change on limiting the gray
	into [0;255] as this is actually done in wgraph.c.

2002-06-10  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/pdf.trm term/svg.trm: Don't use GetColorValueFromFormula()
	mapping for red color when drawing gray output.

2002-06-10  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/README src/color.c: Removed the change of set_color(gray) made
	two days ago. Thus it still calls term->set_color(g) with g=[0:1].
	All drivers are now responsible that they don't overflow for a value
	outside this range.

	term/metapost.trm term/pm.trm term/tgif.trm term/vgagl.trm

2002-06-08  Petr Mikulik  <mikulik@physics.muni.cz>

	[This change removed on 2002-06-10]

	* src/README src/color.c: Routine  void set_color(double gray)  which
	calls term->set_term(gray): do not pass gray >= 1.0 to terminals
	with discrete palette (applies also for postscript if 'set palette
	maxcolors n'). Most terminals currently reference their discrete 
	palette entries (elements in the palette array) by
	   color_number = (int)(gray * sm_palette.colors)
	which goes beyond the upper bounds for gray==1. From now,
	term->set_color(g) will no more get value g>=1.0.

2002-06-08  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.cyg config/makefile.mgw config/makefile.os2:

2002-06-07  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/metapost.trm: In the documentation section, fixed `latex' to
	`latex` --- the reason for doc2rtf to crash.

2002-06-06  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* term/metapost.trm: Add pm3d capability, patch by Arun Persaud

	- implemented 'filledboxes'

2002-05-29  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* lisp/Makefile.in: New install-els target to install the .el
 	files.

2002-05-21  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* docs/gnuplot.doc: Fix misc. typos, reported by Shigeharu Takeno.

	* lisp/*: Update to gnuplot-mode 0.5r.

	* src/unset.c: Define reset_colorbox() static.

	* term/metapost.trm: Patch by Dirk Krause, which includes a previous
	patch by Phillip Wood. New features:
	o A "la$tex" option to switch to LaTeX.
	  In LaTeX mode no \setfont... instructions pointing to "cmr10"
	  are written. Font setup is done in the preamble.
	o An "a4$paper" option to pass the [a4paper] option
	  to the document class. By default this option is not written.
	o The "ps$nfss", "psnfss-v$ersion7" and "nops$nfss" options
	  to include \usepackage instructions for PSNFSS 8, older version
	  or no PSNFSS.
	o The "pro$logues n" (n must be replaced by the number you want)
	  and "nopr$ologues" options to add a "prologues:=2;" line to the
	  output. When using metapost to produce standalone images,
	  "prologues:=2;" causes metapost to include font information into
	  the EPS output.

2002-05-16  Johannes Zellner  <johannes@zellner.org>

	* term/svg.trm: Added shape-rendering:crispEdges to render
 	surfaces correctly, changed color spec to rgb() which is more
 	readable.

2002-05-16  Johannes Zellner  <johannes@zellner.org>

	* term/svg.trm, docs/gnuplot.doc pm3d/README: pm3d support for the
 	svg driver.

2002-05-16  Johannes Zellner  <johannes@zellner.org>

	* term/pdf.trm: Small changes for error messages.

2002-05-15  Johannes Zellner  <johannes@zellner.org>

	* term/pdf.trm, docs/gnuplot.doc, pm3d/README: pm3d support for the pdf
	driver.

2002-05-13  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* configure.in: Fix for broken --without-tutorial option.

2002-05-13  Ethan Merritt  <merritt@u.washington.edu>

	* configure.in: Improved testing for libfreetype dependency in libgd.

2002-05-01  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/gnuplot.doc: Mention PNG supports pm3d.

2002-04-30  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* configure.in: Quoting and cleanup. Should now work with autoconf 2.5x.

2002-04-30  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* term/amiga.trm (AMIGA_linetype): Use mnemonic name L_TYPE_NODRAW
 	in checks for valid linetypes.

	* term/cgm.trm (CGM_linetype, CGM_linecolor, CGM_dashtype): Dito.

	* term/emf.trm (EMF_linetype, EMF_linecolor, EMF_dashtype): Dito.

	* term/fig.trm (FIG_linetype): Dito.

	* term/pdf.trm (PDF_Pen_RealID): Dito.

	* term/svg.trm (SVG_Pen_RealID): Dito.

	* term/svg.trm (SVG_init): Give SVG output a 'viewBox' attribute
 	to make it freely scalable.  This is essentially the same as an
 	PostScript's %%BoundingBox.

	* term/post.trm: Remove explict path from #include of "getcolor.h".

2002-04-30  Lars Hecking  <lhecking@nmrc.ucc.ie>

2002-04-26  Ethan Merritt  <merritt@u.washington.edu>

	New term/gd.trm driver to support PNG and JPEG files by using
 	libgd version 1.8 or greater. Includes support for TrueType fonts,
 	line width, and transparency. Back compatibility option
 	--with-gif=png uses the old gif.trm driver to produce a png image
 	instead.
	
	Files modified:
	    README.1ST		explains choice of GIF or PNG/JPEG
	    term/gd.trm		new file; contains both png and jpeg drivers
	    term/gif.trm	allow PNG_FOR_GIF with new libgd
	    src/term.h		check PNG_FOR_GIF, HAVE_GIF, HAVE_NEWGD flags
	    src/show.c		report configuration options 
	    configure.in	the messy part
	    config/makefile.mgw	totally untested by me
	
	Symbols defined during configuration:
	    HAVE_GIF	# will add gif.trm terminal driver
	    HAVE_PNG	# will have png support (either old or new)
	    HAVE_LIBPNG	# will add png.trm (*old*) terminal driver
	    HAVE_JPEG	# will add jpeg support via gd.trm
	    HAVE_LIBGD	# defined if either the old or new libgd is present
	    HAVE_NEWGD	# defined if new libgd (contains PNG and JPEG support)
	    HAVE_TTF	# support TrueType fonts via new libgd+libfreetype
	    PNG_FOR_GIF	# will trigger dummy gdImageGif definition
	
	Relevant configuration options:
	  --with-gd[=PATH]        specify location of Tom Boutell's gd library
	  --with-jpeg[=PATH]      optionally override location of libjpeg
	  --with-libpng[=PATH]    optionally override location of libpng 
	  --with-freetype[=PATH]  optionally override location of libfreetype
	  --with-gif=png          'set term gif' produces png images instead
	  --with-png[=PATH]       enable *old* png terminal 

2002-04-27  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/graph3d.c src/pm3d.c: Move term->previous_palette(); from
	pm3d.c:pm3d_draw_one() to graph3d.c:do_3dplot(). Fixes plotting
	several color surfaces to postscript files. Maybe the terminal entry
	previous_palette() should be dropped completely as it is used only
	for postscript files to write the palette and all its color surfaces
	in between gsave/grestore.

2002-04-21  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/save.c (save_set_all): Fix quoting of 'set missing' save text.

2002-04-16  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Patch from Dietmar Warning <dwarning@danalyse.de>: 
	
	* term/tkcanvas.trm (TK_put_text): Quote-protect characters that
 	would be interpreted by Tcl/Tk if not in tk_perl mode of
 	operation.

2002-04-10  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* docs/gnuplot.doc: Added missing documentation of timefmt %s
 	specifier to read seconds-since-the-epoch timestamps.

2002-04-08  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/plot2d.c (print_table): Replaced hard-coded axis identifiers
 	of 2002-04-05 patch by those axes actually used by the current
 	dataset, so x2 axis plots will use the x2 format.

	* src/hidden3d.c (in_front): In Test 7, addressed an old FIXME by
 	not declaring an edge invisible if it's entirely inside the 3D
 	triangle.  This fixes a bug where duplicated edges (like the two
 	sides of the seam in a parametric cylinder) would be completely
 	invisible.  OTOH, it brings back some of the old bleed-through
 	type of artefacts, because it can't decide which of two copies of
 	such an edge should be visible.  Before this patch it would draw
 	neither.  Now it draws both.
	(UINT_BITS, COORD_TO_BITMAXK, CALC_BITRANGE) [TEST_GRIDBOX]: Moved
 	these macro definitions towards that of type polygon, which they
 	directly work on.
	(COORD_TO_TREECELL) [TEST_QUADTREE]: Likewise, but moved towards
 	definition of quadtree.
	(in_front): Replaced magic number for size of classification by
 	useful term.
	(general) Several functions re-indented to unify code layout
 	within this module.
	
2002-04-05  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/plot2d.c (print_table): Implemented usage of 'set format'
 	strings by 'set term table' output columns. This has been
 	documented forever, but never correctly implemented yet.  An
 	earlier attempt was incomplete.  Now calls gprintf() to do the
 	actual work, so gnuplot's extended format specifiers like
 	'%s*10^{%S}' also work in table output.  Also added treatment of
 	CANDLESTICKS and FINANCEBARS plot styles.

	* src/plot3d.c (print_3dtable): Likewise, except that the 3D case
 	had been working to some extent, already.  But it didn't support
 	format specifiers other than the standard C ones.

	* src/axis.c (gprintf, mant_exp, decimalsign): Two functions and
 	one global variable move away from here, into util.c.  These used
 	to be private to the axis module, but are now used by other parts
 	of the program, too.

	* src/util.h, src/util.c, * src/axis.h: Likewise.

2002-04-04  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* docs/gnuplot.doc (set margin): Added a small note about the lack
 	of effect of margin settings upon 3D plots.

2002-03-30  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Massively edited contribution from Lutz Maibaum:
	
	* term/post.trm (PS_fillbox) [USE_ULIG_FILLED_BOXES]: Implement
	pattern-filling for postscript, too.  Currently produces a whole
	line of postscript output per pattern line.  This is not very
	elegant compared to a possible implementation as a (set of)
	PostScript macro(s). 
	
2002-03-30  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	Brought in a patch from Stephan Boettcher to add a new command
	"set print". SF Patch # 533094.
	
	* docs/gnuplot.doc (commands->print): Point towards "set print".
	(commands->set->print): Document new option "set print".

	* src/command.c (print_out, print_out_name): New variables to
	store status of 'set print' option.
	(print_set_output, print_show_output): New functions to make it
	accessible to other modules.
	(print_command): Respect new setting by directing all output to
	the specified stream.

	* src/command.h (print_set_output, print_show_output): Prototypes
	added.

	* src/tables.h (set_id): Added enum value S_PRINT.

	* src/tables.c (set_tbl): Added entry for "set/show print"
	command.
	
	* src/show.c (show_command): Handle new case "show print". Added
	to list of options displayed.
	(show_print): New function, implements "show print".

	* src/set.c (set_command): Handle new case "set print".  Added to
	the list of options displayed.
	(set_print): New function, implements "set print".

	* src/unset.c (unset_command): Handle new case "unset print".
	Added to the list of options displayed.
	(unset_print): New function, implements "unset print".

2002-03-28  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/gnuplot.doc: Added many "see web page" and "see demo" so that 
	the URLs to _demo_.html are not so alone. Helps printed gnuplot 
	documentation.

2002-03-26  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/gp_types.h src/datafile.c src/graph3d.c src/hidden3d.c
	src/plot3d.c src/pm3d.c: Do not store the color of a 3D coordinate in
	separate field 'color' of 'struct coordinate', but in the first field
	unused by 3D. This is currently 'ylow', and it gains access by
	'#define CRD_COLOR ylow'. This saves 8 B for each data point.
	  A proposal for the future, aiming to reduce the memory allocated,
	is the complete separation of 2d and 3d coordinates and reorganization
	of their storage...

	* win/wgraph.c: Remove compiler warning.


2002-03-26  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	MS VC++ build patches from John Bollinger <bbands@yahoo.com>:

	* config/makefile.nt (MACHINE): Don't strictly require
 	$PROCESSOR_ARCHITECTURE in their environment variable
	(bf_test.exe): Change "cd" argument to be more portable.
	(clean, veryclean): Avoid error spurious messages by not deleting
 	non-existant files.

2002-03-26  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/command.h src/command.c: Routine do_string() always available
	(only #ifdef USE_MOUSE up to now).

	* src/set.c: Reimplemented "set term push" to issue the complete
	"set term <pushed_name> <pushed_opts>" command.
	Added a hint to set_termoptions().

	* src/show.c: Leading three spaces instead of \t for 'show term' in 
	order to better format terminals with multiline options.

	* term/x11.trm: Let X11_default_command be "gnuplot_x11.exe" for both
	OS/2 and Windows.

2002-03-25  Petr Mikulik  <mikulik@physics.muni.cz>

	* term/x11.trm: Show the expected gnuplot_x11 path if it cannot be
	executed.

	minor modifications. 

2002-03-23  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/axis.h src/axis.c src/datafile.c src/plot3d.c: Fixed color axis
	autoscale. Removed update_pm3d_zrange(). Organize that 
	STORE_WITH_LOG_AND_UPDATE_RANGE(point->color, ...) is called only
	if (NEED_PALETTE(this_plot)).

	* src/gp_types.h: Declare struct coordinate's color only #ifdef PM3D.

2002-03-23  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/term.h: Updates in SHORT_TERMLIST: do not include regis and tek
	terminals for non-relevant platforms.

	* docs/gnuplot.doc (zeroaxis): Add some examples to make the
 	syntax more transparent for newbies.

2002-03-21  Alexander Mai <st002279@hrzpub.tu-darmstadt.de>

	* config/makefile.os2 src/os2/gclient.c: Get it to build again.

2002-03-21  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/os2/gclient.c: Remove my "//PM" tags. Remove encapsulated
	comments due to the 2002-03-16: // => /* */ replacement.

	* config/makefile.os2: Let runtime be dependent on config.h.

	* src/help.c src/pm3d.c src/set.c: Remove compiler warnings.

2002-03-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/graph3d.c (tic_unitz): New variable for truly 3D ticmark
 	lines. Stores z component of tickmark direction routine.
	(draw_3d_graphbox): Extend computation of tic line directions to
 	cover 3 dimensions.
	(xtick_callback, ytick_callback): Make use of new tic_unitz
 	variable, and change all xticks to use term->v_tic, all yticks to
 	term->h_tic.  Fold local variable "dirn" into "scale".

2002-03-16  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/os2/gclient.c: Weeded out all C++-style // comments.
  	CodeStyle disallows them.
	
	* src/pm3d.c (pm3d_plot): Use coordinate field "color" instead of
 	"ylow", for PM3D.
	(filled_color_contour_plot): Changed type of local variable
 	pm3d_color_from_column to TBOOLEAN.

	* src/plot3d.c (get_3ddata): Use coordinate field "color" instead
 	of "ylow", for PM3D.

	* src/graph3d.h (struct surface_points): Changed type of
 	pm3d_color_from_column to TBOOLEAN.

	* src/graph3d.c (plot3d_lines_pm3d, plot3d_points_pm3d): Use
 	coordinate field "color" instead of "ylow", for PM3D.

	* src/datafile.c (df_3dmatrix): Write to coordinate field "color"
 	instead of "ylow", for PM3D. Call STORE_WITH_LOG_AND_UPDATE_RANGE
 	instead of update_pm3d_range.

	* src/gp_types.h (struct coordinate): Add separate element 'color'
 	to avoid the PM3D stuff having to abuse ylow for storing it.

	* src/hidden3d.c (store_vertex): Made color_from_column available
 	in non-PM3D compiles, too. Changed its type to TBOOLEAN.  Use the
 	new "color" field instead of "ylow".
	(build_networks): Have local variable color_from_column regardless
 	of PM3D. Change its type to TBOOLEAN, too.

	* src/plot3d.c (grid_nongrid_data): Dito.

	* src/axis.c (update_pm3d_zrange): Moved #ifdef PM3D inside the
 	function, so it's available, but a no-op, if PM3D is disabled.
  	Put in hacks to avoid -Wunused.
	
	* src/axis.h (NEED_PALETTE) [!PM3D]: Make this #defined in
 	non-PM3D mode, too, for easier coding.
	(update_pm3d_zrange): Moved prototype out of #ifdef PM3D block.
 	
	* src/plot3d.c (calculate_set_of_isolines): Make the 'pal'
 	argument exist independently of PM3D.  Was making the code harder
 	to parse for no benefit.  Add hack to avoid -Wunused warning,
 	instead.
	(eval_3dplots): Changed call accordingly.

2002-03-15  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* term/cgm.trm (struct cgm_properties, cgm_current, cgm_next,
 	cgm_reset): Separate type definition from that of variables.
	(CGM_set_color): Fix off-by-one error in conversion.  Patch from
 	Mike Sutton.

2002-03-12  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/util3d.c (draw3d_point_unconditional): New routine
 	containing the main part of former draw3d_point.  Provides an
 	second entry point to be used by:
	(draw3d_line_unconditional): If v2 is NULL, redirect call to
 	draw3d_point_unconditional.  Moved code before draw3d_line and
 	flagged it GP_INLINE, to make automatic inlining of this routine
 	easier for the compilers.
	(draw3d_point): Call new routine draw3d_point_unconditional to do
 	the real work, if hidden3d isn't applicable.

2002-03-12  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/setshow.h src/set.c src/unset.c docs/gnuplot.doc: Added reset
	for colorbox and palette. 'unset colorbox' resets the default values.

2002-03-11  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/pm3d.c: Fix in get_pm3d_at_option().

	* src/win/wgraph.c src/win/winmain.c: Remove MinGW32 compiler
 	warnings.

2002-03-07  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/titlepag.sty: Changes for the title page of gnuplot.tex:
 	Show up-to-date gnuplot version (from the file VERSION) and the
 	last modification date (from the rcs date tag).

2002-03-07  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

 	HAVE_STRINGIZE): Added these definitions.

	* src/syscfg.h (STRUCT_EXCEPTION_P_X): Moved definition block to
 	here, from internal.c.  Use GP_EXCEPTION_NAME as the name of this
 	structure.  Clarify behaviour by #defining this to be an empty
 	macro if matherr() doesn't take an argument.

	* src/internal.c (GP_MATHERR): Renamed, was matherr.
	(matherr, exception): Removed #defines, as they are no longer
 	useful.

2002-03-07  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* PORTING, config/buildvms.com, config/config.cyg, config/config.mgw,

	instead of ANSI_C.

	* src/internal.c(matherr): Cleaner implementation using autoconf and
	config file based symbols.

	* src/syscfg.h: Don't include ansichek.h. Move __PROTO and generic
	declarations here from ansichek.h. Define fallbacks for
	GP_EXCEPTION_NAME and GP_MATHERR.

2002-02-20  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/axis.c (quantize_normal_tics): Changed name and meaning of
 	first argument: it's now the length of the range to be covered,
 	instead of the log10 of the length. All calls have to be changed!
  	Modified the calculations inside to reduce the risk of FP
 	inaccuracies biting in. In particular avoid possible differences
 	between pow10() and dbl_raise(10.0,).
	(quantize_duodecimal_tics): New function, derived from
 	quantize_normal_tics.  Subdivides ranges with a base-12 rather
 	than a base-10 quantity (--> 60 seconds/minutes, 24 hours, 12
 	months). Uses a stepsize sequence of 1-2-3-6-12 instead of
 	1-2-5-10 in quantize_normal_tics.
	(quantize_time_tics): Calls to quantize_normal_tics changed. Some
 	just had the log10 removed (see above), others were commented out,
 	or replaced by calls to quantize_duodecimal_tics. This is a lot
 	saner than the previous code that piled lots of base-10
 	subdivision attempts on top of each other, and avoids problems
 	with rounding errors, too.
	(time_tic_just): Large parts of this function deactivated ---
 	their work is no longer necessary since the automatically placed
 	will now (almost) always be in the right position already.
	
	* src/contour.c (contour): Changed call of quantize_normal_tics
 	and added a comment what it does.

	gnuplot_x11 driver.
	(parse_driver): Replaced free+alloc by a realloc, and individual
 	comparisons by isspace() calls.  Implemented expansion of gnuplot_x11 
	driver command name by prepending the environment variable

	configure'd X11_DRIVER_DIR if not.
	(X11_init): Use expanded pathname in execvp() calls.

	* term/metafont.trm: Fix typo (lowerrcase instead of lowercase).

2002-01-26  Johannes Zellner  <johannes@zellner.org>

	* pm3d/demo/pm3dColumn.gpi: Quick demo for the new pm3d features.

2002-01-26  Johannes Zellner  <johannes@zellner.org>

	* src/plot3d.c src/plot3d.h src/pm3d.c: Some bug fixes and
 	improvements for the new pm3d functionality.

2002-01-26  Johannes Zellner  <johannes@zellner.org>

	* src/plot3d.c src/graph3d.c src/graph3d.h src/gp_types.h
 	src/hidden3d.c src/pm3d.c src/pm3d.h src/color.c docs/gnuplot.doc:
 	pm3d coloring from an arbitrary data column for data splots
	(column 2 or 4).

2002-01-26  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* configure.in: Added 'exit 0' at end.  Without it make stops
 	after running "config.status --recheck".

	* src/specfun.c: Removed prototypes of former static functions
 	lgampos, lgamneg.
	(lngamma): Added missing return statement.
	(lngamma, inverse_normal_func, inverse_error_func): Moved error
 	message to stderr.

2002-01-25  Johannes Zellner  <johannes@zellner.org>

	* src/plot3d.c: Scaling for 'linetype palette' was broken after
 	the previous changes (at least for 'set pm3d explicit').

2002-01-25  Johannes Zellner  <johannes@zellner.org>

	* src/pm3d.h src/pm3d.c src/set.c src/show.c src/save.c
	src/graph3d.c src/misc.c src/pm3d.c src/pm3d.h src/plot3d.c

	option 'explicit / implicit' and related functionality.

2002-01-25  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/save.c (save_set_all): Removed unused variable. Fixed highly
	probable typo this_arrow->layer in the middle of 'set label'
	treatment.
	
2002-01-25  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS: Added some text from ANNOUNCE-MOUSE.

	* ANNOUNCE-MOUSE: Added a header to that file with two paragraphs 
	which are worth saving, in my opinion. That's a technical docs for
	mouse and its communication.

	* INSTALL: Added section "Running gnuplot on OS/2" from README.os2.

	* docs/old/README.os2: Added a note that this file can be removed.

	* config/makefile.cyg: Added -DHAVE_SLEEP -DNO_SETVBUF.

	* docs/gnuplot.doc: Several small corrections.

2002-01-24  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* FAQ: Updated to current version.

	* tutorial/Makefile.am.in: Rename PLT_SOURCES to PLT_FILES and add
	target for pdf.

	* specfun.c: Remove all code that was labeled for non-commercial use
	only (lgamneg, lgampos, lngamma, inverse_normal_func,
	inverse_error_func). This means that the gamma, inverse normal, and
	inverse error function are not available anymore on platforms that
	don't have native implementations.

2002-01-24  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/doc2tex.c: Replace typesetting of _ from "{\tt\_}" to "\_".

2002-01-24  Johannes Zellner  <johannes@zellner.org>

	* src/readline.c term/x11.trm: Implemented the non-buffered
	stdin for the X11 driver (and ONLY for the X11 driver) to solve
	problems with
	   1) escape sequences (like the "up" arrow),
	   2) pasting commands with the mouse.

2002-01-24  Johannes Zellner  <johannes@zellner.org>

	* src/gplt_x11.c term/x11.trm: Implemented rotated text for the x11
	driver.

2002-01-23  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* docs/gnuplot.doc: Fixed all-spaces line and spurious <TAB>
 	character.

2002-01-23  Petr Mikulik  <mikulik@physics.muni.cz>

	* config/makefile.cyg: Improvements, easily editable options.

	* src/win/wgnuplib.h: _fstr* functions are declared in Cygwin.

2002-01-23  Johannes Zellner  <johannes@zellner.org>

	* term/x11.trm: Split the driver path into words so that something
	like
	    set term x11 driver "strace -f -o strace.out ./gnuplot_x11"
	can be used (nice for debugging for example).

2002-01-22  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/history.c: Fix for "history !first_command_in_history".

	* src/command.c: Fix for "history !load".

2001-01-22  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/graphics.c (boundary): Moved calls to set the axis endpoints
 	up here.  Fixes bug in key placement caused by uninitialized
 	variables used by map_position().
	(do_plot): Removed them from here.
	(boundary): Disallow key entry height to become zero --- want to
 	divide by it later.

2002-01-22  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* INSTALL: Remove references to the GP_PATH_* macros.

	* configure.in: General cleanup and bugfixing. Replace all references
	to GP_PATH_* macros with code that uses generic autoconf macros.

	* src/graphics.c: Make finish_filled_curve() static.

	* VERSION, src/version.c: Increment version to 3.8i, update date
	and copyright.

	* m4/path-hdr.m4, m4/path-lib.m4: Remove.

2002-01-22  Petr Mikulik  <mikulik@physics.muni.cz>

	* NEWS docs/gnuplot.doc src/gadgets.h src/gadgets.c src/graph3d.c
	src/graphics.c src/save.c src/set.c src/show.c src/tables.h

2002-01-18  Clark Gaylord  <cgaylord@vt.edu>

	* Change all references in documentation from gnuplot.org to
	gnuplot.info.

2002-01-17  Johannes Zellner  <johannes@zellner.org>

	* term/x11.trm term/emf.trm: Removed unused variables.

2002-01-17  Johannes Zellner  <johannes@zellner.org>

	* term/x11.trm src/unset.c src/gplt_x11.c: Removed the
	X11_unset_pm3d() function which made multiplot not working on X11.
	Introduced a variable plot->release_cmap in gplt_x11.c for
	controlling freeing of pm3d colors.

2002-01-17  Petr Mikulik  <mikulik@physics.muni.cz>

	* docs/titlepag.tex: Have \usepackage{hyperref} only once.

2002-01-10  Petr Mikulik  <mikulik@physics.muni.cz>

	* pm3d/demo/Demo.gp: Remove 'set term pop' after 'reset' (the latter
	does not change terminal).

2002-01-07  Petr Mikulik  <mikulik@physics.muni.cz>

	* plot.c: Fix load_rcfile() to properly	report the startup filename
	(needed if it contains a typo).

	* misc.c: Fix one c_token++ from yesterday.

2002-01-06  Petr Mikulik  <mikulik@physics.muni.cz>

	src/misc.c src/misc.h src/plot2d.c src/save.c src/set.c src/show.c
	src/tables.c src/tables.h docs/gnuplot.doc NEWS: Implemented options
	for plotting style 'with filledcurves [options]'.

2002-01-03  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* INSTALL: Added paragraph about avoiding floating point exception
 	crashes on Alpha CPUs caused by lack of IEEE compatibility.

2001-12-19  Namio Matuda  <matuda@film.s.dendai.ac.jp>

	* docs/doc2tex.c docs/titlepag.tex: Added some more hypertext
 	facilities into gnuplot.pdf (eg "see `xyz`" makes a link to the
 	page of the section of `xyz`).

	* docs/gnuplot.doc: Typos and fixes for better support of the
 	above.

	* term/be.trm term/gnugraph.trm term/openstep.trm term/next.trm
 	term/tek.trm term/unixplot.trm: Typos and fixes to avoid various
 	LaTeX warnings (eg undefined references and multiply-defined
 	labels) in the preparation of gnuplot.pdf.Introduced definition of
 	TERM_HELP_GNUGRAPH and TERM_HELP_NEXT. Changes labels and
 	START_HELP/END_HELP arguments for gnugraph and openstep.

2001-12-18  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/win/wtext.c: Reallocate larger keyboard buffer instead of
 	silently ignoring input characters coming into an overfull buffer
	(fixes piping 'plot "-" ... e' with large data sets, for
 	instance).
	
2001-12-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* term/epslatex.trm (EPSL_put_text): Fix bug that would output TeX
 	code into the PostScript file.  Report and bugfix by
 	<Ralf_Ahlbrink@web.de>.
	
2001-12-17  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/util.c: Fix graph_error() to avoid gnuplot crash for log
 	axes with negative min/max range value in splot.

	* src/pm3d.c: More appropriate error message for negative cb range
 	and log z axis.

2001-12-16  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/color.c: Fine tuning of the default color box size and
 	position (take in/out/mirror/scale of tics into account). Remove
 	the obsolete code of PUT_ZMINMAX_AROUND used before the cb-axis
 	has been implemented.

	* src/pm3d.c: Remove obsolete comments.

2001-12-14  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/mouse.c: Routine do_event(): Disable event processing for
 	undefined terminals (fixes crash when mouse is on and non-existing
 	terminal is set).

2001-12-14  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/plot2d.c (eval_plots): Yet another fix for linestyle
 	handling.  Plots with no "lt" or "lw" option at all would not get
 	their linewidth, pointsize and other options set up properly.

	* src/plot3d.c (eval_3dplots): Dito.

2001-12-13  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/plot2d.c (eval_plots): Re-do handling of possible
 	duplication of line/point style options. Fixes "plot 2 lt 2, 1 lt
 	1" which would plot both in linetype 1 introduced by Petr's "any
 	order of options" patches.  The line/point style options have to
 	be all together, now. And some codestyle fixes and reindentation.

	* src/plot3d.c (eval_3dplots): Dito.

	* src/misc.c (lp_parse): Codestyle fixes.

2001-12-04  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/axis.c (setup_tics): Went over automatic ticmark extension
 	of axis endpints.  Moved calculation of timelevel[axis] before the
 	tic extension.
	(round_outward): New function. Extracted and recombined code from
 	setup_tics, that handled ticmark extension. Extended to handle
 	time/date axes with their slightly irregular tic steps.
	(make_auto_time_minitics): Added cast to int to quell unsigned
 	comparison warning.

2001-12-04  Alexander Mai <st002279@hrzpub.tu-darmstadt.de>

	* src/fit.c: Fix buffer overflows regarding env vars used for
 	fitting.

2001-12-03  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/save.c (save_set_all): Put #ifdef PM3D around pm3d-only code
 	regions.

	* src/show.c (show_command): Dito.

2001-12-01  Alexander Mai <st002279@hrzpub.tu-darmstadt.de>

	* src/eval.c src/fit.c src/plot.c src/os2/gclient.c
	config/makefile.os2: Abandon EMX non-standard signal processing
	model. Also avoid calling PM-term functions if it's not running.

2001-11-29  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/datafile.c src/misc.c src/plot2d.c src/plot3d.c: Allow
	(nearly) any order of options in plot and splot commands. Actually,
	this "any order" applies separately inside the group of options
	- for a datafile [see df_open() in datafile.c]
		every matrix binary index thru using
	- for plot commands [see plot2d.c]
		smooth title notitle axes with
	- for splot commands [see plot3d.c]
		title notitle with

	* src/tables.h src/tables.c: Comment out plot_tbl[] as (1) it has
	not been used for 2 years, (2) if used any later, it will have to
	be split into datafile_tbl[] and plot_tbl[].

2001-11-29  Guillaume Allegre  <Guillaume.Allegre@imag.fr>

	* docs/gnuplot.doc: Fix inconsistency in the document: many examples
	use the 'set no...' syntax instead of the 3.8-new syntax 'unset'.

2001-11-28  Lars Hecking  <lhecking@nmrc.ucc.ie>

	* src/specfun.c: Remove "non-commercial" clause for ibeta() and
	igamma() by permission of the original author, Jos van der Woude.

2001-11-26  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/graph3d.c: Fix  splot 'a.dat' with ... palette  crash if
	'a.dat' contains a single scan only.

2001-11-25  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/set.c: Allow any order of options in 'set arrow'.
	Fix default value in 'set label' be 'nopoint'.

	* src/show.c: Fix crash in conv_text() for NULL pointer. Fix
	'show label' for labels with no label text specified.

2001-11-24  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/misc.c: Allow any order of lt, lw, pal, ps, pt options in
	'with <style> <options>'. Allow the smooth color change of lines,
	points and dots by syntax 'with <style> palette' instead of 
	'with <style> lt palette' (but keep the parser understanding the
	older syntax too).

	* docs/gnuplot.doc: Better documentation for 'with <style> palette'
	in 'with <style>' section. A section for 'lines' added (currently it
	was commented out).

2001-11-22  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/graph3d.c (do_3dplot) [PM3D]: Handle plot style FILLEDBOXES
 	by falling back to IMPULSES.

	* src/hidden3d.c (build_networks) [PM3D]: Ditto.

2001-11-20  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/set.c (set_label): Corrected as yet un-ChangeLog'ed new code
 	from Petr that allows linetypes to be set for labels and relaxes
	the syntax for that command a lot.

2001-11-10  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/gadgets.h src/mouse.h src/graph3d.c src/graphics.c src/save.c
	src/set.c src/show.c docs/gnuplot.doc NEWS: 'set label' with any
	line type (colour), point type and point size; further allow any
	order of options.

2001-11-07  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/datafile.c (f_column): Added missing implementation of
 	'column(-2)' in using expressions.  Removed offset by one of value
 	held in "column" variable to de-obfuscate the code a bit.

2001-11-01  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* NEWS: Lots of additional fixes and new features mentioned, and
 	some entries moved to the correct release they came with.

2001-10-31  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/axis.h src/axis.c src/graphics.c src/save.c src/set.c
 	src/unset.c src/show.c src/graph3d.c docs/gnuplot.doc NEWS: New
 	options for 'set grid': {layerdefault | front | back}.

	* src/save.c: Labels and arrows were not saving "back", "front"
 	option.

2001-10-31  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/graph3d.c (boundary3d): Fix computation of current aspect
 	ratio by casting input variable to double.

2001-10-26  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/color.c term/tgif.trm term/pm.trm term/gif.trm term/fig.trm
	term/cgm.trm: The first and the last colour ranges in 'set palette
	maxcolors' were different (half of the range) than the "inner"
	colour ranges. I.e. now	the discrete palette drivers have the 
	set_color(gray) routine coded like
	    int gif_color = (int)( gray * sm_palette.colors );
	instead of the previous
	    int gif_color = (int)( gray * (sm_palette.colors-1) + 0.5 );
	Some other drivers have already this code, so all is unified now.

	* term/post.trm: If 'set palette maxcolors', then the colour for the
	last colour box [(colors-1)/colors; 1.0] should equal the last colour
	from the mapping formulae, as for the discrete palette drivers.

	* src/win/wgraph.c: Support for 'set palette maxcolors'.

2001-10-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

        * win/pgnuplot.c (cbGetTextWindow): Revert return value to behave
        like the documentation of the EnumThreadWindows() Win32 API call
        expects it.

2001-10-11  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/graph3d.c (boundary) Add code to handle `set size square' or
 	`set size ratio <number>' for 3D plots, too. Code essentially
 	copied out of the one found in 2D equivalent function `boundary'.
	(boundary3d): Remove stale argument `scaling' and code trying to
 	use it --- term->scale() was disallowed long ago.
  	(do_3dplot): Remove local variable `scaling' and code
 	setting/using it.

	* src/graphics.c (boundary): Remove unused argument 'scaling'
	(do_plot): Remove local variable `scaling' which used to be passed
 	to boundary(), where it wasn't used anyway.

2001-10-11  Dick Crawford <crawford@arete.com>

	* term/post.trm (PS_header): Old PostScript linewidth patch for
 	dotted axis linetype finally brought into 3.8 branch. Affects
 	macros /BL, /AL, /UL, and /LTa. /UL macro fixed to avoid problems
 	with dash pattern length definition for zero linewidth.

2001-10-10  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/color.c (draw_color_smooth_box) [PM3D]: Change order of
 	operations to ensure setup_tics() sees the COLOR_AXIS as
 	log-scaled, if it is.  Use new AUTOSCALE_FIXMIN and
 	AUTOSCALE_FIXMAX flags instead of a blunt AUTOSCALE_NONE override
 	to avoid extending the color box beyond the useful z range.

2001-10-06  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/set.c docs/gnuplot.doc: New autoscale option:
	`set autoscale keepfix` autoscales all axes while keeping the fix
	settings.

	* src/mouse.c: Let hotkey 'a' do `set autoscale keepfix` instead
	of `set autoscale`.

2001-10-05  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/plot3d.c (grid_nongrid_data): Fix bug in code to handle the
 	case of a sampling point falling exactly onto one of the input
 	data points, by adding a break statement to bail out of the inner
 	loop.

2001-10-05  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/show.c (SHOW_AUTOSCALE): Use new local variable to make code
 	more readable.  Only output " (min)" or " (max)" if they're not
 	both on.  Don't print an extra TAB if non-parametric. Start a new
 	line occasionally, to make avoid overly long output lines.

	* src/mouse.c (apply_zoom): New static variable autoscale_copies
 	to remember the state of 'set autoscale'.  Zooming overwrites
 	this, so it has to be recovered at 'unzoom' time.  Fill
 	autoscale_copies upon the initial zoom that leaves 'un-zoomed'
 	state, and restore it whenever "previous zoom" or "unzoom"
 	builtins return to the original settings.  Resized internal string
 	buffer to allow for longer mouse-generated command.
	(OUTPUT_AUTOSCALE): New macro to help with that task. Visible only
 	inside apply_zoom().
	(apply_zoom): Save the `set_{min|max}' fields instead of
 	`{min|max}' for retrieval by "previous zoom" or "unzoom" builtins,
 	as those represent the user-serviceable parts of the status.

2001-10-03  Petr Mikulik  <mikulik@physics.muni.cz>

	* pm3d/contrib/pm3dConvertToImage.awk: Fix for a too early "stroke"
	in converting colour images (replace "/g {stroke" by "/g {Stroke").

2001-10-02  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/axis.c (gen_tics): Renamed local variable `ticmin' to
 	`internal_min', to match its twin `internal_max' in one block.
  	Don't round internal_{max|min} outwards if ticstep is ridiculously
 	large. This effectively turned off tic position clipping, and
 	would lead to coordinate overflow in terminal drivers.

	* term/debug.trm (DEBUG_arrow): Corrected type of argument `head'
 	to TBOOLEAN.

	* term/gif.trm (GIF_make_palette): Fix incorrect call of debug macro
	FPRINTF().

2001-10-01  Slaven Rezic  <slaven.rezic@berlin.de>

	* term/tkcanvas.trm: No more warnings if running with perl -w. Take
	-highlightthickness into account for height/width computation. Use
	a subroutine reference rather than a subroutine name in the perl
	version (as in my original patch). Doc fix for perl sample.

2001-09-28  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/graphics.c (plot_c_bars): Changed candlesticks behaviour to
	ignore order of high and low prices, as was long since claimed by
	the docs, but not actually done in the code.

	* docs/gnuplot.doc: Corrected documentation about candlesticks
	behaviour if open and close prices are exchanged.  Some spurious
	whitespace removed to please 'make check'.

2001-09-27  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/set.c docs/gnuplot.doc: New autoscale option:
	`set autoscale {{axis}{...|fix} | fix}` to easily set fixmin and
	fixmax in one command for one or all axes.
	* src/unset.c: Wrong indentation of two "}" in unset_autoscale().

2001-09-19  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	* src/gplt_x11.c (GR_MAKE_PALETTE, GR_RELEASE_PALETTE,
	GR_SET_COLOR, GR_FILLED_POLYGON): Renamed so they all have an X11_
	prefix now, like their copies in x11.trm.
	(exec_cmd): Extend parsing of GR_FILLED_POLYGON case to allow for
	large polygons being broken into several lines. Uses new static
	variables `saved_npoints' and `saved_i' to keep state from one
	partial line to the next.

	* term/x11.trm (X11_filled_polygon): Protocol for filled_polygon
	call changed. Now uses continuation lines to break up large
	polygons like those you get from Petr's filledcurves feature.
	Incomplete lines have an "xxxx" at their end; continuations are
	flagged by a -1 in the number-of-points field.

2001-09-19  Petr Mikulik  <mikulik@physics.muni.cz>

	* src/win/wcommon.h src/win/wgnuplib.c: New routine
	LocalReAllocPtr().

	* src/win/wgraph.c: Dynamically allocate enough memory for a
	polygon with many corners (fixes 'plot with filledcurves').

2001-09-19  Alexander Mai <st002279@hrzpub.tu-darmstadt.de>

	* INSTALL docs/gnuplot.doc: Fix old URLs (use gnuplot.org now);
	add hyperlinks. Move pointers to frontends for gnuplot.

	* configure configure.in docs/Makefile.in: Let configure 
	check for even more utils which we use. Always check for emacs.

2001-09-18  Alexander Mai <st002279@hrzpub.tu-darmstadt.de>

	* src/readline.c: Fix Gnuplot-readline implementation to
	distinguish between VIO and xterm on OS/2.

2001-09-18  Hans-Bernhard Broeker  <broeker@physik.rwth-aachen.de>

	The remainder of Uli Gruenebaum's filled boxes implementation,
	reviewed and massively changed by me.

	* term/win.trm (WIN_boxfill): Renamed from WIN_filledbox.
	Parameter `linetype' renamed to `style'.
	(WIN_boxfill) [USE_ULIG_FILLEDBOXES]: Send a W_fillstyle opcode to
	tell the new code how the interior of the rectangle is to be
	filled.

	* src/win/wgraph.c [USE_ULIG_FILLEDBOXES] (halftone_bitmaps,
	halftone_num, halftone_brush, halftone_bitdata, halftone_bitmap,
	pattern_bitmaps, pattern_num, pattern_brush, pattern_bitdata,
	pattern_bitmap, brushes_initialized): New file-scope variables to
	implement fillbox extension.

	(DestroyPens) [USE_ULIG_FILLEDBOXES]: Delete brushes here.
	(drawgraph) [USE_ULIG_FILLEDBOXES]: Implement drawing of filled
	boxes. W_fillstyle gives the style, a W_move specifies the top
	left corner, and the (x,y) pair sent with the W_boxfill specifies
	the width and height of the box.

	* src/win/wgnuplot.mnu: Added menu entry for filledboxes style.

	* src/win/wgnuplib.h (WGNUPLOTVERSION): Increased to reflect API
	extension.

	filled_polygon(). Syntax:
	     set style [data | function] filledcurves [options]
	     plot ... with filledcurves [options]
	Options are not yet implemented -- this is let as a homework
	for somebody else.

	* term/x11.trm: Don't crash on X11_ipc overflow when "too many"
	vertices passed into X11_filled_polygon(). This should be properly 
	fixed by an X11 programmer according to the hint therein.

	descriptive name.
	(make_tics): Remove local variable l10, and. Extracted the timetic

	Unused code and variables commented #if'ed out. Use new
	t_timelevel names.
	(setup_tics): Fix bug with fixed-increment series ticks on
	time/data axes. timelevel[axis] wasn't defined at all, in that
	case, using whatever value was left in there from the previous
	plot. BAD thing.
	(gen_tics): Call of make_ltic() renamed.
	(time_tic_just): Type of "level" argument changed to t_timelevel.
