xgetech
get the current graphics scale
Calling Sequence
[wrect, frect, logflag, arect] = xgetech()
Arguments
- wrect, frect
real vectors.
- logflag
string of size 2
"xy"
.
Description
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.
Examples
// 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();
