Re: palette with ppl command

[Stephen Nash <s.d.nash@xxxxxxxxxxxxx>]

Tony,

One way would be to define an extra 'level' as such on top of your normal
pallet that would cover these extreme values

/levels(0,1e6,5e5)(1e8)/

this would create your pallet from 0 to 1e6 with 5e5 spacing but add another
level to 1e8 to cover extreme values so that they're a pretty colour rather
than white!

                Hi all,

Well, I have another question about palette in Ferret.
I usually define the level of the palette to have good details in the maps, but there's always some place where the field is out of the range (saturate palette). In this case, Ferret put some white, could we plot the last color of the palette instead ?

Hi Claire Livingston,
                       You can specify the palette you want in two ways

    1. set a particular palette for the whole ferret session
         yes? palette=no_green_centered

    2. set a particular palette for a particular fill command
         yes? fill/hlim=**:**:**/vlim=**:**:**/palette=no_green_centered var

 ppl fill will not take any arguments like palette. You can use the /set
qualifier to the fill command and use go unlabel and ppl fill to get rid
of the label you don't want. Have a trial with the attached script.

Hope this helps ...

With Regards

Jaison
