TypeError: boxplot() got an unexpected keyword argument 'labels'

Question

I'm using ipython 3.2.0, and I'm trying to use boxplot. Online documentation and examples suggest that a keyword "labels" should exist, as also stated in this SO post, but I get the following error:

TypeError: boxplot() got an unexpected keyword argument 'labels'

Was the labels keyword removed? If so, what is the official way to get a legend for a boxplot?

Solution 1

The labels kwarg was added in https://github.com/matplotlib/matplotlib/pull/2643, first shipped with mpl v1.4.0 and is still present on master.

Solution 2

The solution did not work for me (Python 33 on Windows). I found another way and leave it here just in case someone else may need it:

1. Uninstall the old version: pip uninstall matplotlib
2. Download the wheel file from here https://pypi.python.org/pypi/matplotlib/1.4.3
3. Run pip install path_to_whl_file
