[ferret_users] Palette with different colours about a fixed point

[Samrat Rao <samrat.rao@xxxxxxxxx>]

Hi,

I am using Ferret 6.1. I would like to have different colours about a point, say 0. For ex:

fill/lev=(-10,20,1)/pal=newone var

In this case i would like, say, shades of blue below 0 and shades of red above 0. This is possible by explicitly creating a spk file that is defined by fixed points. But i would like to use the same palette for other levels as well, but all must have shades of blue below 0 and shades of red above 0. Something like a mix between defining colours by percentage and by fixed points.

I hope i am able to convey my requirements. Could someone say whether this has a simple solution?
