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



I don't th!ink ferret distributes palets with a white band in the middle. You will have to create it yourself.

Here is an exemple : 
   0.0   80.0    0.0  100.0
   10.0   30.0   20.0  100.0
   45.0    0.0  100.0    0.0
   45.1  100.0  100.0  100.0
   54.9  100.0  100.0  100.0
   55.0  100.0  100.0    0.0
   60.0  100.0   80.0    0.0
   78.0  100.0    0.0    0.0
   82.0   80.0    0.0    0.0
   92.0   60.0   50.0   50.0
  100.0  100.0   75.0   75.0


You may also want to suppress the 0 level, which something like

SHADE/LEV=(-10,10,1)DEL(0)

I don't know how you can use DEL(0) with LEV=10H

Hi Fabio,

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.

That's a nice question.  I have some ideas, but other people may have better ones.  In addition, the email messages are archived and searchable and therefore are a great resource for future users.  So, why don't you post the question to the Ferret mailing list? 

Cheers,
Ryo
