Given a list A and a ListPlot of A how can the plotting points be color coded by the values in list B?
A={{1,1},{2,2},{3,3},{4,4},{5,5}}; B={Red,Red,Blue,Blue,Blue};
This has to be an easy task than I am making difficult. Help please.
You could wrap the point data values in Style, something along the lines of:
ListPlot[{Style[{1,1},Red], Style[{2,2},Blue],etc..}]
This is described in the documentation for ListPlot if you drill down into Scope and then Wrappers.
This will do the trick.
A = RandomReal[{0, 10}, {10000, 2}]; B = RandomChoice[{Red, Green, Blue}, 10000]; AB = GatherBy[Thread[{A, B}], Last]; col = AB[[All, 1, 2]]; points = AB[[All, All, 1]]; ListPlot[points, PlotStyle -> col]
