Hi,
your idea should work. The only problem is that the argument of Hue should be between 0 and 1.
A dirty idea of doing this may be like the following:
Graphics[{Hue[(#3 - Min[dalist /. {x_, y_, z_} -> z])/
Max[(dalst /. {x_, y_, z_} -> z) -
Min[dalist /. {x_, y_, z_} -> z]]], Point[{#1, #2}]}& @@@
dalist, Axes -> {True, True}]
Try it. Have fun.
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,
