A couple matplotlib tutorials.
Both are primarily iPyhton notebooks.
To view / run them, navigate to the folder they are in:
$ cd matplotlib/Tutorial1 $ ipython notebook
And your browser should be brought up with a index tp the notebooks in a main window.
The first one is nice, but short and sweet.
The second one is longer, and really gets into the internals of MPL -- so a really good idea if you want to do more than basic plotting.
Thanks to the authors of these -- acknowledged in the doocs themselves.
