[gradsusr] how to create quantile scale

[Ondrej Vlcek]

Dear GrADS users,
 I would like to create a quantile color legend in which all the colors would 
represent an equal area in the map. Up to now I have been using cbarn.gs which 
works fine, but there is a problem if the dataset has some large peak - then 
most of the map is plotted in the same color and that's something I would like 
to change...
Does anyone know about some already existing tool?

Regards,
Ondrej
