I am using some of scripts from a year ago before we upgraded to
IDL5.2.1.
Before I was able to overlay filled contours atop a map background using
the command:
contour, value, longitude, latitude, /Fill, $
background=white, /overplot , /Follow, $
c_thick=1.5, nlevels=20, c_colors=ccolors, $
levels=clevels, C_Charsize=0.5
Where value, longitude and latitude are 2-D arrays of equal size.
Have there been any unexpected changes?
Thanks much

Not to my knowledge. That looks like a perfectly valid Contour
command to me. Although I don't think the Background keyword
will do anything, since you aren't erasing the display (as
a result of the Overplot keyword).
Cheers,
David

Hi Bill,
In case you are using SGI IRIX, as we do, this is indeed a bug that was
introduced by RSI in IDL5.2.1 -this forced us to keep the old 5.1 in
parallel with 5.2.1 for a long time. It has been corrected in IDL5.3
Greetings, Ole
