[ncl-talk] weird color shown in plots

[Rick Brownrigg]

Hi Ming,

I just tested this from home, and I can't reproduce the issue. I copied the
NCL script directly from the directory you cited in the original email. I
had it write to both X11 and PNG workstations, and I'm getting the correct
colors. I simply do a "module load ncl" upon logging in to cheyenne.

Something just occurred to me -- do you by chance have a file name
".hluresfile" (note the leading ".") in your home directory, and does it
have an entry for "*wkColorMap"?  (Note if its prefixed with a "!", its
commented out)

Rick
