You might want to try
g.reset()
or something of the sort.

i saw this post because I'm also trying to figure out gnuplot.py
I can't seem to find proper documentation anywhere.
  unless its telling me to run "demo.py" and analyse the code.
does any1 have any idea where else I could look? A comprehensive
tutorial/online documentation would 
be ideal
