Thanks for all the help, guys! The affected computer is at home, but I'll address all these issues before I post again with my fix.
James: It's on my personal box, and I've got reiserfs. David: OS: GNU/Linux 2.4 (Gentoo) Python 2.3 GNUplot 1.6 I just checked the Gentoo Portage tree and 1.7 is listed "~x86" (unstable), so unwittingly I had gotten 1.6 when I emerged gnuplot-py. Definitely, the first thing I'm going to do is upgrade to 1.7. Before I do, though, I'll try to see if this works: Gnuplot.GnuplotOpts.prefer_fifo_data = 0 Gnuplot.GnuplotOpts.prefer_inline_data = 1 It sounds like Paul had the same problem. I'll also try the "binary = 1" before I upgrade. Fernando, that's a creative solution, I'll try it as well... while 1: if os.path.isfile(your_plot_filename): break time.sleep(1) Thanks guys! -- http://mail.python.org/mailman/listinfo/python-list
