How do I plot hatched bars using Pandas and Matplotlib?

MatplotlibPythonData Visualization

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()

Output
