Hi, I have a list of data with coordinates and intensity value, such as
{{0.0028989,0.332549,1.75},{0.334769,0.395588,2.},{0.469562,0.0831043,
3.},{0.693715,0.672036,4.},{0.0111101,0.227195,1.75},{0.974097,0.623733,
3.75},{0.905734,0.980701,4.},{0.766471,0.0168064,3.},{0.543011,0.512028,
3.25},{0.472721,0.573379,3.5}}
I want to be able to listplot the first 2 elements of each row as the
coordinate on R^2, and the third as color of the coordinate. I used
scatterplot3d and the result was not ideal. I wrote my own function to get
the colors to work, but I figure there is probably some builtin function
that has better options and color scheme than the one I'm doing. Is any
such one out there.
Thanks in advance,
Ming
