And default style is changed.

Here is ho I used to have boxplot on matplotlib python 2

recent version on python 3 look different and seem not to take into account parameters passed to it.

Plot generated with

In [1]: %pylab
In [2]: boxplot(np.random.normal(size=500), sym='ro')
In [3]: matplotlib.__version__
Out[3]: '1.4.x'

(yes I know pylab is wrong)

git-desribe in mpl repo before a python3 setup install gives v1.3.1rc2-1231-gef462e4

My github foo did not show similar issues.
