This appendix contains several examples of plot files generated using
many of the \wip\ commands described in this manual.
Because of the obvious limitations of print, commands like {\tt color} are
omitted from this appendix.
Wherever possible, each command is followed by a comment statement.
While these comments, marked by the comment
character\index{Comments} (\#),\index{Comments!comment character(\#)}
are not required, they do provide information as to why certain commands
are included or are necessary to generate a certain aspect of a plot.
The user is strongly encouraged to include comments whenever possible;
especially in macro definitions.
All plots in this appendix may be reproduced by typing the commands
listed in the accompanying plot files.
\begin{description}
\item[Figure~\ref{p:basic}] is a very basic plot demonstrating many of the
commands that control the simple graphical attributes described
in Chapter~\ref{c:concepts}.
\item[Figure~\ref{p:simple}] demonstrates how to read data in from
an external file.
\item[Figure~\ref{p:text}] shows several examples of how to annotate a plot
with text and also illustrates the various fonts available in \wip.
\item[Figure~\ref{p:greek}] displays the lower and upper case Greek letters
and the Roman characters needed to generate them.
\item[Figure~\ref{p:panel}] presents a simple example of how to partition
a single plot surface into sub-regions or panels;
illustrates the various ways that the
{\tt box}\index{Commands!{\tt box}}\index{Boxes!commands!{\tt box}}
command may be called;
and demonstrates how to define and pass arguments to a macro\index{Macros}.
\item[Figure~\ref{p:cos}] presents a more complicated example of how to use
macros and how to generate array entries.
This example also illustrates the use of the {\tt set} and {\tt loop}
commands.
\item[Figure~\ref{p:symbol}]\index{Symbols!markers} plots the
standard graph markers used by the
{\tt symbol}\index{Commands!{\tt symbol}}\index{Symbols} command.
\item[Figure~\ref{p:hershey}]\index{Symbols!Hershey symbols} continues
the previous example by illustrating how to display the Hershey
symbols used by \wip. The macro, as listed, will display all
currently available Hershey symbols, but only the first page is shown
in this example.
This example also makes use of macros\index{Macros},
panels\index{Commands!{\tt panel}}, and the
{\tt loop}\index{Commands!{\tt loop}} command.
\item[Figure~\ref{p:fit}] is an example of how to generate a fit
and display it. The different methods of fits are illustrated.
\item[Figure~\ref{p:image}] is a simple example of how to generate an
image halftone and wedge and also lists a typical header for a
FITS\index{FITS}\index{Images!image formats!FITS} image file.
\item[Figure~\ref{p:image2}] expands on the previous example by
demonstrating how to extract a subimage and display it in a
different region on the view screen. In addition, it illustrates
the power of user variables\index{User Variables} and macros in
moving to various regions of the display.
\item[Figure~\ref{p:overlay}] expands on the previous two image examples by
showing how to overlay two images that have different resolutions.
\begin{htmlonly}
\item[Figure~\ref{p:cimage}] is the same as Figure~\ref{p:image}
except that it is done in color.
\item[Figure~\ref{p:palettes}] displays a collection of color palettes.
This example makes use of the {\tt loop} and {\tt wedge} commands.
