Re: Points conditionnal Coloring

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,
