Re: [ferret_users] data-adapted centered palette with white always at zero

Thank you Ryo and Olivier,

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.

Thanks
