I have a data file containing three columns. I'd like to plot (1st, 2nd) and use the 3rd to produce a colour-map. That is, each point in the plain takes a colour that depends on the value in the third column.
Using Gnuplot, I can easily do that:
gnuplot> set palette rgbformulae 33,13,10
plot "output.dat" using 1:2:3 with points palette
For a set of data I get something like this:
Now, is there a straightforward way of doing this in Mathematica?
