Add sharex and sharey to grouped boxplot

danfrankj · danfrankj · commit a17f9d77c6ac · 2014-08-12T14:57:57.000-07:00
sharex and sharey should be settable and by default False in a grouped boxplot. E.g. 

In [97]: df = DataFrame(np.random.rand(10,2), columns=['Col1', 'Col2'] )

In [98]: df['X'] =['A','A','A','A','A','B','B','B','B','B']

In [99]: df.iloc[0:5, :2] += 10000

In [100]: df.groupby('X').boxplot()  # this is unreadable
