How to create a seaborn.heatmap() with frames around the tiles?
To make frames around the tiles in a Seaborn heatmap, we can use linewidths and linecolor values in the heatmap() method.
Steps
- Set the figure size and adjust the padding between and around the subplots.
- Create a Pandas data frame with 5 columns.
- Use heatmap() method to plot rectangular data as a color-encoded matrix.
- To display the figure, use show() method.
Example
import seaborn as sns import pandas as pd import numpy as np import matplotlib.pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True df = pd.DataFrame(np.random.random((5, 5)), columns=["col1", "col2", "col3", "col4", "col5"]) sns.heatmap(df, linewidths=4, linecolor='green') plt.show()
