Re: Asymmetric legend colors

Two options are simplest.

First, you can tell NCL specific colors to use for your choice of
cnMaxValF/cnMinValF/cnLevelSpacingF.
Just set an array of color indices in cnColors = (/ ... , ..., .../), or
set cnColors to be the actual colors you choose, if you're using an
up-to-date version of NCL.

Your other option is to create a custom color table with only the colors
you want in it. You can se that up as described here:

http://www.ncl.ucar.edu/Document/Graphics/create_color_table.shtml

Depending on your situation and the number of colors you want to use,
either option can have its advantages.
