Re: [Matplotlib-users] no plots showing
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.
http://matplotlib.org/faq/usage_faq.html#what-is-a-backend
Note that the MPLBACKEND environmental variable was not added until
matplotlib 1.5

You're missing a pair of parentheses.

plt.show is a function. You are not calling it just displaying it.
