Hello,

I have success with the following:
#+begin_src python :results output raw :exports results
   import numpy, matplotlib, matplotlib.pyplot
   figure = matplotlib.pyplot.figure()
   axes = figure.add_subplot(111, title=u"Hello", xlabel="x",  
ylabel="y")
   x = numpy.arange(-10, 10, 0.1)
   axes.plot(x, x**2)
   figure.savefig("/tmp/plot_test.png")
   figure.clf()
   print "[[/tmp/plot_test.png]]"
#+end_src

You get only the figure as a result, and not the code.
This method executes the code at each export. The alternative is to  
set ":exports none" , to execute with C-c C-c and then to delete the  
"+results:" line so that the result is exported.

Pierre
