[Tutor] Non-blocking non-interactive graphics display

You should look at IPython it is a frontend for the Python interpreter 
that runs the eventloop of Matplotlib in a separate thread. 

http://ipython.scipy.org/moin/

Matplotlib and Ipython might be in your Python distribution from 
Enthougt.

A session with Ipython looks like this:

In [2]:#A window with a graph has appeared. One can pan and zoom this 
graph.

In [3]:1+2+3
Out[3]:6

In [4]:
-----------------------------------------------------

In the Matplotlib newsgroup you would have to ask how to draw 
graphical primitives (lines).

HTH,
Eike.
