.TH xsetech 2 "April 1993" "Scilab Group" "Scilab Function"
.so ../sci.an
.SH NAME
xsetech - set the sub window of a graphic window to use for graphics
.SH CALLING SEQUENCE
.nf
[]=xsetech(wrect [,frect,logflag])
.fi
.SH PARAMETERS
.TP 10
wrect
: a vector of size 4 (sub window definition)
.TP 10
frect
: a vector of size 4 (just like the rect argument of \fVplot2d\fR )
.TP 10
logflag
: a string of size 2 "xy", where x and y can be "n" or "l". "n" for
normal and "l" for logscale. x is for the x-axis and y for the y-axis.
.SH DESCRIPTION
.LP
This function is mainly used to set the sub window of the graphic window
which will be used for graphics. The sub window is specified with the
parameter \fVwrect=[x,y,w,h]\fR ( Upper-Left Width Height ).
The values in \fVwrect\fR are specified using proportion of the width
or height of the current graphic window. for example
.LP
\fVwrect=[0,0,1.0,1.0]\fR means that all the graphic window will be used.
.LP
\fVwrect=[0.5,0,0.5,1.0]\fR means that the graphic region will be the right
half of the graphic window.
.LP This function also set the current graphic scales for 2D plottings
and can be used in conjunction with graphic routines which request
the current graphic scale (for example \fVstrf="x0y"\fR in \fVplot2d\fR ).
\fVfrect=[xmin,ymin,xmax,ymax]\fR is used to set the graphic scale and
is just like the \fVrect\fR argument of \fVplot2d\fR. Its default value
is \fV[0,0,1,1]\fR.
.SH EXAMPLE
.nf
//In this first example xsetech is used to split the graphic window
//in two parts
// xsetech is used to fix the first sub window
// and the graphic scale
xsetech([0,0,1.0,0.5],[-5,-3,5,3]);
// then we call plot2d with the "001" option to use the graphic scale
// set by xsetech
plot2d((1:10)',(1:10)',1,"001",' ');
// xsetech is used to fix the second sub window
xsetech([0,0.5,1.0,0.5]);
// the graphic scale is set by xsetech to [0,0,1,1] by default
// and we change it with the use of the rect argument in plot2d
plot2d((1:10)',(1:10)',1,"011",' ',[-6,-6,6,6]);
//A second example with four graphics on a single graphic window
xset("font',2,0);
xsetech([0,0,0.5,0.5]);plot3d();
xsetech([0.5,0,0.5,0.5]);plot2d();
xsetech([0.5,0.5,0.5,0.5]);grayplot();
xsetech([0,0.5,0.5,0.5]);histplot();
// back to default values for the sub window
xsetech([0,0,1,1]);
xset("default');
