Hello,
I want to make a concentration plot, that is I have a large amount of x-y
coordinates, and the vast majority congregate around three points on the
plane. I would like to show that in a graph, either with a density plot that
would show three dark spots corresponding to the concentration there, or a
3d plot that would have z values corresponding to the number of x-y values
in a small area. I suppose I could just test all the values to see which
"grid" it falls into, and then color that grid the appropriate intensity or
z value. Is this the best way? Is there a more elegant method? Thank you so
much.
