How do I plot hatched bars using Pandas and Matplotlib?

To plot hatches bars using Pandas, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Make a dataframe using Pandas with two columns.
Add an axes to the current figure as a subplot arrangement.
Make a plot with kind="bars" class by name.
Make a list of hatches.
Get the bars patches using bars.patches.
Iterate bars patches and set the hatch of each patch.
To display the figure, use show() method.

Example

import numpy as np
import pandas as pd
from matplotlib import pyplot as plt

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

df = pd.DataFrame(np.random.rand(5, 2), columns=['a', 'b'])
ax = plt.figure().add_subplot(111)
bars = df.plot(ax=ax, kind='bar')
hatches = ["*", "/", "o", "x"]

for patch in bars.patches:
   patch.set_hatch(hatches[np.random.randint(10)%len(hatches)])

plt.show()
