I had a quick play with your charting library and it looks good. If I
can offer a feature request....

Doing animated (i.e. updated @ about 1-2Hz, moving window and fixed
scaling, or infrequent axis autoscaling) large timeseries datasets in
matplotlib is painful. If your library could provide some sort of api
like

p = Plot(animated=True, x=None, y=[])
for i in range(0,10000000:
    p.add_y(42)

This would give a nice animated line plot (like gnome system monitor).
It should be smart about when it rescales the Y axis, if/when it adjusts
the x axis, and only redraws the new point and parts of the data in
screen.

I will buy you beers

Thanks

John
