[Mne_analysis] mne-python saving epochs drop log plot

[Kambiz Tavabi]

Thanks Denis. I finally got this thing to work. For anyone who is
interested; I edited my matplotlib config file setting for backend to
use Qt4agg and set the bindings for the backend to pyside i.e., the
specific modifications I made in the matplotlibrc file are:

`backend: Qt4agg`
`backend.qt4 : PySide`

cheers,
Kam

P.s. The alternative to PySide is PyQt4, which does not appear to be on
good terms with the Anaconda python environment. I believe it is not
available for install through their repositories, and I was also unable to
find it via `pip`. PyQT4 depends on a module called SIP that installs
rather painlessly after downloading source and building, however I
encountered lots of ugly errors trying the same approach with PyQT4...TBC
