Yes, simple and undocumented. This is one of those
things I say--like I used to say "Device,
Decomposed=0"--every chance I get, but it never sinks in,
no matter how many books or articles I write. I happened
to mention it in the presence of some Excelis engineers a
couple of months ago and they looked at me like I was daft.

Let me say it again. If you think colors have meaning,
and should match the values in your colorbar (I realize
this excludes the 2-3 people using the function graphics
colorbar who don't care about any of this), then you
MUST use CELL_FILL instead of FILL when you put filled
contour plots on a map projection. You will get incorrect
results if you do otherwise!

Cheers,

David
