set the sub-window of a graphics window for plotting
xsetech(wrect,[frect,logflag]) xsetech(wrect=[...],frect=[..],logflag="..", arect=[...]) xsetech()
vector of size 4, defining the sub-window to use.
vector of size 4.
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.
vector of size 4.
xsetech is mainly used to set the sub-window of the graphics
window which will be used for plotting. The sub-window is specified
with the parameter
wrect=[x,y,w,h] (upper-left point, width,
height). The values in
wrect are specified using proportion of
the width or height of the current graphic window. For instance
wrect=[0,0,1,1] means that the whole graphics window will be
wrect=[0.5,0,0.5,1] means that the graphics region
will be the right half of the graphics window.
xsetech also set the current graphics scales for 2D plotting and
can be used in conjunction with graphics routines which request the
current graphics scale (for instance
frect=[xmin,ymin,xmax,ymax] is used to set the graphics scale
and is just like the
rect argument of
frect is not given the current value of the graphic scale
remains unchanged. the default value of
(at window creation, when switching back to default value with
xset('default') or when clearing graphic recorded events
arect=[x_left, x_right,y_up,y_down] is used to set the graphic
frame inside the subwindow. The graphic frame is specified (like
wrect) using proportion of the width or height of the current
graphic subwindow. Default value is
arect is not given, current value remains unchanged.
