SHOW

Defines the graphics unit-of-measure isotropically.
 
 SHOW left,right,bottom,top
 
Usage:
SHOW -10,20,0,75
SHOW Left,Right,Bottom,Top
Description:
SHOW, like WINDOW, specifies the values to be displayed within the VIEWPORT or the hard-clip boundaries. They can be any units of measure you wish to work with (inches, miles, years, etc.).
The SHOW and WINDOW statements differ in how they map data onto the viewport. SHOW uses isotropic units (the X and Y units are of equal length); whereas WINDOW may use non-isotropic units (the X and Y units are of different lengths).
A SHOW image can be "mirrored" about the X or Y axes by reversing the order of the limits for each dimension by specifying the high value before the low value.
