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();```
