well -- I was trying to figure out why the divergence from R's boxplot
help, but so far it seemed to match description/definition for boxplot
as in matplotlib.  I guess the next step would be to look "inside"
(running apt-get source r-base now ;-) )

would you may be interested to adopt (or just do independently) an
option to e.g. plot the data point?  once I shared this one
http://nbviewer.ipython.org/url/www.onerussian.com/tmp/run_plots.ipynb
and the actual code https://gist.github.com/yarikoptic/9023331

I just never got to formalize it into mpl pull request :-/
