[Python] Give a title to the colorbar with Seaborn heatmap

Overview

When you create a heatmap with seaborn, you also want to give a title to the color bar.

This time, I will introduce how to do it.

Method

Do as follows.

import numpy as np
import matplotlib.pyplot as plt
import seaborn as sns

x=np.random.randint(0, 10, (8, 8))

fig, ax=plt.subplots()
ax=sns.heatmap(x)
ax.collections[0].colorbar.set_label('Colorbar Label')
plt.show()

Properties can be changed with the argument of set_label ().

//omit

ax.collections[0].colorbar.set_label('Colorbar Label', labelpad=20, fontsize=14)

//omit
