How to make custom grid lines in Seaborn heatmap?
To make custom grid lines in 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 dataframe with 5 columns.
Use heatmap() method to plot the 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()
