Mary.
Thank you. By the way does this type of question fall under the
ncl-install listserve? I didn't know or I would have posted there.
I looked at my .hluresfile and its an exact copy as the .hluresfile
from the NCL http://www.ncl.ucar.edu/Document/Graphics/hlures.shtml
page.
My setting for "wkColorMap" is
*wkColorMap : rainbow+gray

But ....
I just commented out this line with a "!"
!*wkColorMap : rainbow+gray

and now I am getting the right colors, the default colormap, when I do
example 2. This seems backwards. Should this line be commented out by
default? I didn't change my colormap settings anywhere else.
Sincerely,
Bold
