matplotlib: plot multiple columns of pandas data frame on the bar chart

Question

I am using the following code to plot a bar-chart:

import matplotlib.pyplot as pls 
my_df.plot(x=\'my_timestampe\', y=\'col_A\', kind=\'bar\') 
plt.show()
         


        

Answer 1

Although the accepted answer works fine, since v0.21.0rc1 it gives a warning

UserWarning: Pandas doesn't allow columns to be created via a new attribute name

Instead, one can do

df[["X", "A", "B", "C"]].plot(x="X", kind="bar")
