    I'm sorry we didn't respond to you. The chaco-users mailing list is not
    well-subscribed or well-trafficked, but the 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.
