I forgot to mention: Hue alone doesn't do the job. It always scales to the range of the data. Also, Hue[2/3(1- # Max[data])]& seems to work, but is there a better way? sh I previously wrote: > Let's say we're solving the heat equation on [0,1]x[0,1] numerically > with an initial temperature distribution with values in [0,1], and > we're displaying the solution with ListDensityPlot as it evolves over > time.
