pandas.core.groupby.DataFrameGroupBy.boxplot¶
- DataFrameGroupBy.boxplot(grouped, subplots=True, column=None, fontsize=None, rot=0, grid=True, ax=None, figsize=None, layout=None, **kwds)¶
Make box plots from DataFrameGroupBy data.
Parameters: grouped : Grouped DataFrame
subplots :
- False - no subplots will be used
- True - create a subplot for each group
column : column name or list of names, or vector
Can be any valid input to groupby
fontsize : int or string
rot : label rotation angle
grid : Setting this to True will show the grid
ax : Matplotlib axis object, default None
figsize : A tuple (width, height) in inches
layout : tuple (optional)
(rows, columns) for the layout of the plot
kwds : other plotting keyword arguments to be passed to matplotlib boxplot
function
Returns: dict of key/value = group key/DataFrame.boxplot return value
or DataFrame.boxplot return value in case subplots=figures=False
Examples
>>> import pandas >>> import numpy as np >>> import itertools >>> >>> tuples = [t for t in itertools.product(range(1000), range(4))] >>> index = pandas.MultiIndex.from_tuples(tuples, names=['lvl0', 'lvl1']) >>> data = np.random.randn(len(index),4) >>> df = pandas.DataFrame(data, columns=list('ABCD'), index=index) >>> >>> grouped = df.groupby(level='lvl1') >>> boxplot_frame_groupby(grouped) >>> >>> grouped = df.unstack(level='lvl1').groupby(level=0, axis=1) >>> boxplot_frame_groupby(grouped, subplots=False)
