I want to create a histogram with broken axes and found that there must be a module doing this called brokenaxes that works together with matplotlib (source) . Anyway, when I trie to import the module like this:

import matplotlib.pyplot as plt
from brokenaxes import brokenaxes

I get this error message:

No module named brokenaxes

I'm using ipython5.1 in anaconda 4.3.

Can anyone help me?

In order to use a module it has to be installed. This can be done via

pip install brokenaxes

See https://docs.python.org/3/installing/

However, it seems that the brokenaxes you get from the python package index is currently (as of June 2017) broken (as the name says it ;-)). It should now (as of August 2017) be working again (see answer by package maintainer below).

Alternatively go to https://github.com/bendichter/brokenaxes, download the files and copy brokenaxes.py into your python's site-packages folder.
