Thread: [Matplotlib-users] Matplotlib lag on windows seven

Hello everyone,

I've just changed my computer from a old core 2 duo on windows Xp to a
intel Xeon with 12 Gb Ram. I've installed matplotlib but I plot a graph
it's about 10 times slower than windows Xp to pan the axis or move the
graph. Even if I'm plotting something very simple like that:

from pylab import *

x = [0,1,2]

plot(x,x)

show()


Do you have any idea?


Thanks,


Fabien

Which backends are you using on each platform.  A difference there is 
the most likely culprit.

It is probably coincidence, but I noted MPL running way faster when I
stopped using QT4Agg and upgraded to 1.2.0.

Try upgrading and report back.

I have installed MPL 1.2.0 but it's still laggy...
