Aye. But I think 5 days is not too much to ask for ;-) >> Maybe the graph generation could be tweaked, or a simple, traditional 2D >> lines plot could be used instead? > > I could add the option for 2D graphs as well.

Piping to gnuplot usually works very well for me. Thinking more of it, I think a scatter plot would be better for a graph with many discontinuities. (800 data points on 600 pixels are no problem for gnuplot, haven't tried with much more yet, but I think it scales well). Moritz -- Moritz Lenz http://moritz.faui2k3.org/ | http://perl-6.de/
