To add units to a heatmap annotation in Seaborn, we can take the following steps −
Set the figure size and adjust the padding between and around the subplots.
Create a 5×5 dimension matrix using numpy.
Plot rectangular data as a color-encoded matrix.
Annotate heatmap value with %age unit.
To display the figure, use show() method.
Example
import matplotlib.pyplot as plt import seaborn as sns import numpy as np plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True data = np.random.rand(5, 5) ax = sns.heatmap(data, annot=True, fmt='.1f', square=1, linewidth=1.) for t in ax.texts: t.set_text(t.get_text() + " %") plt.show()
