Hi Matt, you may create a plot using graphic primitives. E.g. assume you have your data as 4-tupel, where the first element gives the state of the point, e.g. 0 and 1: dat={{0, 0, 0, 0}, {1, 1, 1, 1}, {0, 0, 0, 1}, {1, 1, 0, 0}} We can now use the first element to generate the wanted color: Show[Graphics3D[ { If[#[[1]]==0, Hue[0.5],Hue[1]], Point[Rest[#]]}& /@ dat ], Axes -> True] Matt Thompson wrote: > Folks, I'm wondering if it's possible to add a dimension to a ScatterPlot3D in the form of color? I have a Perl script that generates a list of {x,y,z} for a SP3D from a molecular dynamics trajectory, and it does work, but the plot is just mono. > > Rather, I'd like to change the color of certain points depending on the state the trajectory is on at that time.
