get the current graphics scale
[wrect,frect,logflag,arect]=xgetech()
:wrect,frect real vectors. : :logflag string of size 2 “xy”. :
xgetech returns the current graphics scale (of the current window). The rectangle [xmin,ymin,xmax,ymax] given by frect is the size of the whole graphics window. The plotting will be made in the region of the current graphics window specified by wrect.
wrect=[x,y,w,h] (upper-left point, width, height) describes a region inside the graphics window. The values in wrect are specified using proportion of the width and height of the graphics window:
wrect=[0 0 1 1] means that the whole graphics window is used.
wrect=[0.5 0 0.5 1] means that the graphics region is the right half of the graphics window.
logflag is a string of size 2 “xy”, where x and y can be “n” or “l”. “n” stands for normal (linear) scale and “l” stands for logscale. x stands for the x-axis and y stands for the y-axis.
arect=[x_left, x_right,y_up,y_down] gives the frame size 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 1/8*[1,1,1,1]. If arect is not given, current value remains unchanged.
// 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])
