Useful options to do what I want. Is there any way to set 0 to a
particular color, or to have 0 to be white? Still the lev=10C puts the 0
at the center but I don't understand how 0 values are colored because I
see either val>0 or val<0 on the legend.
That's a nice question. I have some ideas, but other people may have better ones. In addition, the email messages are archived and searchable and therefore are a great resource for future users. So, why don't you post the question to the Ferret mailing list?
Cheers,
Ryo
