Doug, Hey, you're first in line! This is driving me crazy...my program worked and then it stopped working. I should have gone to lunch when it worked :) When it did work, I was getting two X axes and two Y axes (when superimposing 2 data sets). Go figure. Re: adding the same map twice...each pass I make a new map (new as in "valueMap = new ScalarMap(...)"). That's why I find the exception perplexing. Thanks for your help, though. I'll go through the code again and see what's not right. p Doug Lindholm wrote: > > I was going to reply, but I figured someone would beat me to it since I > get these messages later than most.
