python - Difficulty in plotting Pandas Multi-indexed DataFrame or series -

please see image

s = pd.dataframe(combined_df.groupby(['session','age_range', 'gender']).size()) s.head(25)

this how multi-indexed data frame looks like. trying plot data in such way can compare male , female users of different age groups active during different sessions(say morning, evening, noon , night). example plot male , female users of age group 0-17, 18-24, 25-29... during different sessions have.

note: have tried few examples stack overflow , other websites still unsuccessful in getting need. so, request guys try solving problem , me in finding solution this. have been struggling many days , documentation vague. so, please throw light on problem. ]2

i think can use unstack dataframe.plot.bar:

import matplotlib.pyplot plt df = combined_df.groupby(['session','age_range', 'gender']).size() df.unstack(fill_value=0).plot.bar() plt.show()
