xsetech(2) Scilab Function xsetech(2)
NAME
xsetech - set the sub window of a graphic window to use for graphics
CALLING SEQUENCE
[]=xsetech(wrect [,frect,logflag])
PARAMETERS
wrect : a vector of size 4 (sub window definition)
frect : a vector of size 4 (just like the rect argument of plot2d )
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.
DESCRIPTION
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 wrect=[x,y,w,h] ( Upper-Left Width Height ). The values in wrect
are specified using proportion of the width or height of the current
graphic window. for example
wrect=[0,0,1.0,1.0] means that all the graphic window will be used.
wrect=[0.5,0,0.5,1.0] means that the graphic region will be the right half
of the graphic window.
and can be used in conjunction with graphic routines which request the
current graphic scale (for example strf="x0y" in plot2d ).
frect=[xmin,ymin,xmax,ymax] is used to set the graphic scale and is just
like the rect argument of plot2d. Its default value is [0,0,1,1].
EXAMPLE
//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');
