[ncl-talk] control legend values

[mireiyue]

Dear NCL users,

I want to create a legend that shows minimum -1000 and maximum 10000. I want to have different interval for negative and positive values. And I am using gsn_define_colormap(wks,"ViBlGrWhYeOrRe”) and I want to put white color for zero.

I haven’t found any information about this work. 

I will appreciate any related helps and comments.

Thank you
