Re: spread color plot in opt@pltColorMap

Dear NCL,
Thanks for the suggestions, yes now everything is good enough,
I will start to play with diagnostics_**cam.ncl and also try to change some
codes inside it esp for wkspace analysis.
Anyway, thanks a lot to Dennis and Marry for your "to-do point" suggestion!
