I'm sorry we didn't respond to you. The chaco-users mailing list is not 
well-subscribed or well-trafficked, but the enthought-dev at enthought.com mailing 
list is. We haven't done a good job of letting new people know they should be on 
the chaco-users list to answer questions or updating the documentation to point 
users to enthought-dev instead.

Anyways, to answer your question, we have several examples of how one sets up a 
plot then updates it with new data:

I can't help much with the PySerial part, I'm afraid. Integrating that with the 
GUI event loop is probably going to be the trickiest bit.
