As Eric said Github master works with PySide. If you can't wait for a
release and you don't want to run the Github version of MPL you can use
the following code to render a plot inside a PySide app. Note that this
will just show the plot image. You won't get the tool bar, status bar
or any other GUI elements.

Hi All,
I have tried the sample PySide code given at
http://www.scipy.org/Cookbook/Matplotlib/PySide
the below excerpt is from my "Python Shell" for this sample code, which
gives this error,
Github master works with pyside. It is expected to emerge as a release
within a few weeks.

"ImportError: Warning: formlayout requires PyQt4>v4.3"
It seems that it is looking for PyQt; but the whole point of using
PySide is to avoid using PyQt.
Any help is appreciated.
