Re: How to plot individual 2D data points, where each must have its own color.

Hi Chrisantha,

How about this?  Generate some data
	data = {#, Random[], Random[]} & /@ Range[32];

And plot it
	temp = Graphics[{Hue[data[[#, 3]]], PointSize[.02], Point[{data[[#,
1]],
             data[[#, 2]]}]}] & /@ Range[Length@data];
	Show[temp, PlotRange -> {0, 1}, Frame -> True];

Regards,

Dave.
