Thread: [Matplotlib-users] matplotlib figure within Qt Application -> segfault

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.
