Re: About colormap

Hi,

Versions of NCL prior to the 6.1.0-beta have a 256 color limit. Often
times you can set resources like gsMarkerColor in just the way you
mention, provided one uses a colormap with less than 256 entries.
 However, the WhiteBlue colormap you mention has used all 256 colors
defining shades of white and blue.

These restrictions will be largely eliminated in NCL 6.1.0.
