How can I add textures to my bars and wedges in Matplotlib?

To add textures to bars and wedges we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Create a new figure or activate an existing figure using figure() method.
Add an axes to the figure as part of a subplot arrangement.
Make a list of hatches. Bars could be filled with some hatches.
Create number bars as equivalent to number of hatches.
Use bar() method to plot the bars with different hatch.
To display the figure, use show() method.

Example

import numpy as np
from matplotlib import pyplot as plt

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

fig = plt.figure()
ax = fig.add_subplot(111)
textures = ["//", "*", "o", "d", "."]

for i in range(len(textures)):
   ax.bar(i, np.random.randint(1, 5), color="green", edgecolor="black", alpha=0.3, hatch=textures[i])

plt.show()
