[Matplotlib-users] how to update plots fast

[RazAlon <raz...@we...>]

Hi,

I wish to have several (about 3) plots which are updated about once per
second, as part of some application that's monitoring an instrument.

I set pyplot to interactive mode. I create as many figures as I need, and
then I simply plot to them whenever I have new data coming in (each time I
plot a new x and y vectors, I don't know if it's possible just to append
data points to existing plots).

I work on windows xp with the default matplotlib settings.

This procedure is very slow. The plots take ages to update.

Is there a faster way to do that?

Thank you,
Raz
