Contour Colors on Maps [message #70429]

Folks

I just spent a couple of hours puzzling over the colors of
a filled contour plot on top of a map projection. I could
have spent the time more profitably by reading some of the
contouring articles on my web page. :-(

Let me just give you the bottom line, before you go out
and publish those beautiful pictures. If you are putting
filled contours on *map projections* use the CELL_FILL and
not the FILL keyword. If you don't, your colors will
surely lead to eventual embarrassment.

Cheers,

David
