.TH xgetech 2 "April 1993" "Scilab Group" "Scilab Function"
.so ../sci.an
.SH NAME
xgetech - get the current graphics scale
.SH CALLING SEQUENCE
.nf
[wrect,frect,logflag,arect]=xgetech()
.fi
.SH PARAMETERS
.TP 13
wrect,frect
: real vectors.
.TP 13
logflag
: string of size 2 "xy".
.SH DESCRIPTION
\fVxgetech\fR returns the current graphics scale (of the current window).
The rectangle [xmin,ymin,xmax,ymax] given by
\fVfrect\fR is the size of the whole graphics window.
The plotting will be made in
the region of the current graphics window specified by \fVwrect\fR.
.LP
\fVwrect=[x,y,w,h]\fR (upper-left point, width, height) describes a region
inside
the graphics window. The values in \fVwrect\fR are specified using proportion
of the width and height of the graphics window:
.LP
\fVwrect=[0 0 1 1]\fR means that the whole graphics window is used.
.LP
\fVwrect=[0.5 0 0.5 1]\fR means that the graphics region is the right
half of the graphics window.
\fVlogflag\fR is a string of size 2 "xy", where x and y can be "n" or "l".
"n" stands for
normal and "l" stands for logscale. x stands for the x-axis and y stands
for the y-axis.
\fVarect=[x_left, x_right,y_up,y_down]\fR gives the frame size
inside the subwindow. The graphic frame is specified (like \fVwrect\fR)
using proportion of the width or height of the current graphic subwindow.
Default value is \fV1/8*[1,1,1,1]\fR. If \fVarect\fR is not given,
current value remains unchanged.
.SH EXAMPLE
.nf
// first subwindow
xsetech([0,0,1.0,0.5])
plot2d()
// then xsetech is used to set the second sub window
xsetech([0,0.5,1.0,0.5])
grayplot()
// get the graphic scales of first subwindow
xsetech([0,0,1.0,0.5])
[wrect,frect,logflag,arect]=xgetech();
// get the graphic scales of second subwindow
xsetech([0,0.5,1.0,0.5])
[wrect,frect,logflag,arect]=xgetech();
xbasc();
xset('default')
