Use index in pandas to plot data

Question

I have a pandas-Dataframe and use resample() to calculate means (e.g. daily or monthly means). Here is a small example.

import pandas as pd  
i         


        

Answer 1

Also,

monthly_mean.plot(x=df.index, y='A')

Answer 2

Try this,

monthly_mean.plot(y='A', use_index=True)

Answer 3

You can use reset_index to turn the index back into a column:

monthly_mean.reset_index().plot(x='index', y='A')

Answer 4

monthly_mean.plot(y='A')

Uses index as x-axis by default.
