That makes sense. The agg backend is a non graphical backend intended for
saving image output. I don't know why this is the default one on your system.
if you start your python session with:
```
import matplotlib
matplotlib.use('TkAgg')
...
```
You will select the TkAgg backend which is interactive and normally installed.
I don't know which ones are available on your system but see the link below for
various possibilities that you may try instead. This also contains information
about how the backends are set.

Note that the MPLBACKEND environmental variable was not added until matplotlib
1.5
