I want to plot points with 3d coordinates like this <a
moz-do-not-send="true" href="http://twitpic.com/8dj7r4">http://twitpic.com/8dj7r4</a>
but I need to assign them with different colors, so that I can
have a different color for each "cluster".<br>
how do I do that? and perhaps with bigger points, so that they are
better visible ;).<br>
<br>
thanks in advance, Andreas<br>

hi<br>
<br>
you lay proceed this way:<br>
<br>
for each cluster<br>
plot points in the cluster<br>
change color<br>
change mark style and size<br>
next cluster<br>
<br>
<br>
change color :<br>
e=gce()<br>
e.mark_mode = "on"; e.surface_mode = "off"<br>
e.mark_foreground=4 //this will chose a color according to the
current color map. you can also use any RGB color :
e.mark_foreground=color(255,123,123)<br>
<br>
change marks : <br>
use : <br>
e.mark_style<br>
e.mark_size<br>
<br>
(have a look at help mark_style)<br>
<br>
<br>
here is an example (without the loop on the clusters)<br>
<br>
plot3d<br>
e=gce()<br>
e.mark_mode = "on"; e.surface_mode = "off"<br>
e.mark_foreground=color(255,123,123)<br>
e.mark_style = 0<br>
e.mark_size = 5<br>
e.mark_size = .6<br>
<br>
<br>
hope this helps<br>
