I am plotting one column of a pandas dataframe as line plot, using plot() :
df.iloc[:,1].plot()
and get the desired result:
Now I want to plot another column of the same dataframe as bar chart using
ax=df.iloc[:,3].plot(kind='bar',width=1)
with the result:
And finally I want to combine both by
spy_price_data.iloc[:,1].plot(ax=ax)
which doesn't produce any plot.
Why are the x-ticks of the bar plot so different to the x-ticks of the line plot? How can I combine both plots in one plot?
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
some data
df = pd.DataFrame(np.random.randn(5,2))
print (df)
0 1
0 0.008177 -0.121644
1 0.643535 -0.070786
2 -0.104024 0.872997
3 -0.033835 0.067264
4 -0.576762 0.571293
then we create an axes object (ax). Notice that we pass ax to both plots
_, ax = plt.subplots()
df[0].plot(ax=ax)
df[1].plot(kind='bar', ax=ax)
