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}]

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,
