Why is the Hue wrong? data = RandomReal[{0, 1}, {50, 3}]; ListPointPlot3D[data, ColorFunction -> Function[{x, y, z}, Hue[z]], PlotRange -> {{-0.1, 1.1}, {-0.1, 1.1}, Automatic}, ViewPoint -> {.5, .5, 10}] Graphics[{Hue[#3], Point[{#1, #2}]} & @@@ data, PlotRange -> {{-0.1, 1.1}, {-0.1, 1.1}}, Axes -> {True, True}] Bob Hanlon ---- Louis-Alexandre <laeh at nyu.edu> wrote: ============= Hi, I am trying to plot some points, and color them according to a particular Value. dalist is of that kind : {{x1,y1,z1},{x2,y2,z2},... ,{xN, yN,zN}} So I need a simple 2D plot where the color of the point will depend on the z value. What I have : Graphics[{Hue[#3], Point[{#1, #2}]} & @@@ dalist, Axes -> {True, True}] Obviously this Hue[] is wrong. Many thanks fo any help you could provide,
