HELP: Density of Points on Scatterplot [message #405]

Help! I am trying to create a scatterplot of 2 Landsat Image bands (ie
band 4 vs band 5) for clustering purposes and I need to be able to determine
the density of points on the plot. I have tried to create a 256x256 z array
by looping through the images, but this takes forever with images of any
size. Does anyone have any suggestions?

Jon
