@rcollyer Yeah. Basically, I generate lots of ListDensityPlots from a large dataset, then want to use a different ColorFunction for a select one or two of them. . - Eli Lan plot is a graphics object, it does not retain information of the underlying mathematical function used to construct it (i.e. you cannot access the z values). ). You can replace the VertexColors in the graphics object, but. I love Mathematica notebooks, for analytical calculations, prototyping algorithms, and most of all: plotting and analyzing data.
