Setting ColorFunction->Hue makes for pretty density plots but it makes
both really low and really high areas red; I'd like to distinguish between
them.
Here is how I solved that problem:
ColorFunction -> (Hue[-.83 # + .67]&)
It uses deep blue for low regions and bright pink for highest regions.
If others have played with aesthetically pleasing ColorFunctions, I'd love
to hear your thoughts, experiences, improvements to the above...
Here is a little code snippet I used to experiment:
m = -.83;
c = .67;
n = 30;
ListDensityPlot[{Range[0, n], Table[Mod[i, 2]*n, {i, 0, n}]},
Mesh -> False,
ColorFunction -> (Hue[m # + c]&)];
(* top row alternates between lowest and highest regions;
bottom row goes from lowest (left) to highest (right) *)
Thanks!
Daniel
