Ok yall, here's my summary. Thanks again for all the help. Most importantly, upgrading to gnuplot-py 1.7 fixes this problem.
In gnuplot-py 1.6, this is the bottom line... Does not fix: Gnuplot.GnuplotOpts.prefer_fifo_data = 0 Fixes: Gnuplot.GnuplotOpts.prefer_inline_data = 1 Fixes: (placed between setting output and plot) while 1: if os.path.isfile("myGraph.png"): break time.sleep(1) As for matplotlib, I checked it out. Looks amazing! I really, really like what demos I tried. HOWEVER, I could not find a good way to do smoothing. I like the gnuplot bezier smoothing. This wouldn't be the hardest thing in the world to code, but I was a little disappointed. If yall have any ideas, bring em on! :) -- http://mail.python.org/mailman/listinfo/python-list
