RE: plot coloring



Try this:
t=Table[{Random[],Random[]},{5}];(*two dimensional coordinates*)
l=Line@t;(*a line to join the points*) p=Point/@t(*transforms
coordinates into graphic primitive Point*)
c:=RGBColor[Random[],Random[],Random[]](*graphic directive you can make
a function of your points*)

Show[Graphics[{l,Map[{c,PointSize[1/30],#}&,p]}]]

Hope this helps,

Objet:	[mg10444] plot coloring

Hola, all;
  I'm looking for a way to color lines.  Say I have a data set
{{{x,y},...{xn,yn}},{{x1,y1}....{xn1,yn1}},.....} and I want to plot
each of the points in the set with different colors.  I've tried using
Map to change the values of r,g,b but they all change byt the same
amount, thus, the lines are always the same color.  How do I vary r,g,b
selectively and uniquely so that I get different colors for each line?

Great site and thanks for all the help!

Paul Hanson
