disipyl is a wrapper around dislin. It includes a class that lets plots appear inside tkinter frames. I did a quick test and the first demo plot (run tkdisipyl.py) of a 180 point sine and cosine plotted at over 100 Hz. http://kim.bio.upenn.edu/~pmagwene/disipyl.html http://www.mps.mpg.de/dislin/ -- http://mail.python.org/mailman/listinfo/python-list
