Matlabplot is a very flexible graphics library, but unfortortunately it can be sometimes difficult to get a backend to work on a machine without root access.

With root privileges:

sudo yum install python34-tkinter

Without root: ?

* PyQT4/5


To change the backend:
```bash
cat <<EOF >> ~/.config/matplotlib/matplotlibrc
backend : Qt4Agg
EOF

Unfortunatetly, PyQT4/5 cannot be installed from pip https://github.com/pypa/pip/issues/2157
