[gradsusr] how can i delete or clean shade or contour that there is outside of shape (*.shp) on map ?

[Stephen McMillan]

Alireza,
Do you have a shapefile for areas surrounding your area of concern?  If so,
use the polygon fill option to draw the external area after you display
your variable.  If not, check out the "admin98" shapefile that should be in
your GrADS library (in SupportData).
