Re: Black and white shadding plot for positive and negative values

Hi Dennis:

Thank you very much for letting me know the possible examples in NCL website.

http://www.ncl.ucar.edu/Applications/coneff.shtml example 10 is close to what I want.

However, it would be much better if the texture is the same for positive values or negative values, respectively, and the value levels are denoted by shading with darker shade for larger values.
