Have you reported it? > Is there a way around this that anybody knows of? Just playing around, I found that they probably just got confused with the order of arguments. This gives the same plot in version 7 as the code you gave for version 6: ListDensityPlot[Table[Sin[i + j^2], {i, 0, 3, 0.05}, {j, 0, 3, 0.05}], ColorFunctionScaling -> False, ColorFunction -> Function[{x, y, z}, Hue[x]] ] hth, albert
