matplotlib figure within Qt Application -> segfault

Community matplotlib-users

Hi,

I have a Qt application, where I want to display a matplotlib figure which
is updated from time to time (not mebeded, in its own window).

Now, I do:
import pylab

pylab.ion()
pylab.figure()

within a function of the Qt application. And then I get a segfault.

What is the proper way to do this?
I use matplotlib 0.99.1.1 on gentoo linux.

Thanks!
Nathan

You don't want to use the pylab interface to integrate a figure into a
qt application. Instead, see the example at
http://matplotlib.sourceforge.net/examples/user_interfaces/embedding_in_qt4.html
, it will show you how to create a plot in a separate window and
update it periodically.
