I've run into this problem so often with map projections
and MAP_GRID that I have had to write my own MAP_GRID
routine to deal with it. Basically, what I had to do
is write my own "clipping" routine that checks to see
if the point I am trying to draw is inside the boundary
given by the !X.CRANGE and !Y.CRANGE vectors. If it is,
I draw the point, if it is not, I don't.
It's a bit of a pain to write wrappers for all of IDL's
graphics routines. :-(
Cheers,
David
