Pandas: Bar-Plot with two bars and two y-axis

Question

I have a DataFrame looking like this:

     amount     price
age
A     40929   4066443
B     93904   9611272
C    188349  19360005
D    248438  24335536
E             


        

Answer 1

You just need to write: df.plot( kind= 'bar', secondary_y= 'amount')

import matplotlib.pyplot as plt
import numpy as np
import pandas as pd
from io import StringIO
s = StringIO("""     amount     price
A     40929   4066443
B     93904   9611272
C    188349  19360005
D    248438  24335536
E    205622  18888604
F    140173  12580900
G     76243   6751731
H     36859   3418329
I     29304   2758928
J     39768   3201269
K     30350   2867059""")
df = pd.read_csv(s, index_col=0, delimiter=' ', skipinitialspace=True)

_ = df.plot( kind= 'bar' , secondary_y= 'amount' , rot= 0 )
plt.show()
