xgetech - get the current graphics scale

### Calling Sequence

  `[wrect,frect,logflag,arect]=xgetech()`

### Parameters

- `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();
    xbasc();
    xset('default')
