In addition to the other responses (all of which I liked), a couple of other alternatives to consider are 2D density plots (see ?kde2d in the MASS package, for example) or geom_tile() in the ggplot2 package, which you can think of as a 3D histogram projected to 2D with color corresponding to (relat

Hi, One solution could be to subsample the data, or jitter the data (give it some random noise). A more elegant solution, imho, is to use a 2d histogram (3d histogram is not a good alternative, I think it is much better to use color instead of a third dimension). I don't think this is easy to mak
