I would suggest not using the pylab interface. Try building off of one of the 
embedding_in examples in 
http://matplotlib.sourceforge.net/matplotlib_examples_0.90.0.zip.

Also, rather than repeatedly reading your data file to determine when new data 
is available, I suggest using os.path.getmtime.
