Fast plotting of many data points in Python?


I am programming a oscilloscope module in Python. For this reason, I
want to plot very many data points as fast as possible. This can be
more than 100 000 at once. So far I have been using the ploting module
of wxPython. However, it becomes unstable for more than 25000 points.
Can someone recommend me a faster plotting library? It would be really
cool if one could embed this in wxPython. If someone has an idea I
would be very glad about answer.

With kind regards,
