Plot clipping

You may specify a clipping area for drawing graphics primitives such as lines and strings. When you do a display command, GrADS sets the clipping region to the parea, draws the graphic, then sets the clipping region to the entire page. Even if you have set the clipping region, a display command will reset it to the entire page. To clip the display of the various draw commands:
set clip xlo xhi ylo yhi

where xlo,xhi,ylo,yhi are the clipping coordinates in real page inches.
