Re: [ferret_users] Customized palette

So, you want the white near zero values whatever the entire contouring
range is.  I guess that's a tall order.

You could normalize your variable in such a way as to bring zero to the

   let newvar = if var gt 0 then var/maxpos else var/maxneg
   fill/palette=whatever_centered newvar

when var's range is (-maxneg, maxpos).

But in this case, you would have to fix the colorbar manually.
