matplotlib + pyside

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,

“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.

Github master works with pyside. It is expected to emerge as a release within a few weeks.

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.
