How do I select a color for every point in Gnuplot data file?

Question

I want to plot points, each with X, Y and a color. How do I do that in Gnuplot?

Answer 1

You can try something like this:

Line plot in GnuPlot where line color is a third column in my data file?

For example:

plot "./file.dat" u 1:2:3 with points palette

where file.dat contains your data, the first column is the x axis and the second column is the y axis, the third column is the colour.
