Re: Runtime Error - Need Advice
I can now reproduce this. It seems the same old problem that PythonWin can not reliably run matplotlib because successive runs of the script use the same interpreter. Ipython should work. Append pylab.close() to your script; at least it will not crash on the second run. -- Christoph On 2/9/2010 10:44 AM, Lee Boger wrote:(Continue reading)> > Although, if I close the figure then re-run the script, a new figure > pops up but it doesn't have any data plotted.
