Here is how I do use gnuplot from Python:

import os
gnuplot=os.popen('gnuplot -persist','w')
commands="""\
set title 'Simple diagram'
plot x*x
"""
gnuplot.write(commands)
gnuplot.close()
print "Done"

Actually, my first usage of Python, a while back, was to generate
gnuplot code ;) BTW, what that graphics does mean, for mere mortals
who don't know Dutch?
