# 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();
