How to show the title for the diagram of Seaborn pairplot() or PridGrid()? (Matplotlib)

To show the title for the diagram for Seaborn pairplot() or PairGrid(), we can use the fig.suptitle() method. This adds a centered title above all subplots in the figure.

Steps

• Set the figure size and adjust the padding between and around the subplots
• Create a Pandas DataFrame with sample data
• Plot pairwise relationships using pairplot() or PairGrid()
• Add a centered title to the figure using fig.suptitle()
• Display the figure using show() method

Example with pairplot()

Here's how to add a title to a seaborn pairplot ?

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=["a", "b", "c", "d", "e"])

pp = sns.pairplot(df, height=2.0)
pp.fig.suptitle("My Pairplot Title")

plt.show()

Example with PairGrid()

You can also add titles to PairGrid objects in the same way ?

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

# Create sample data
df = pd.DataFrame({
    'x': np.random.normal(0, 1, 100),
    'y': np.random.normal(0, 1, 100),
    'z': np.random.normal(0, 1, 100)
})

# Create PairGrid
g = sns.PairGrid(df)
g.map_diag(sns.histplot)
g.map_upper(sns.scatterplot)
g.map_lower(sns.scatterplot)

# Add title
g.fig.suptitle("Custom PairGrid with Title")

plt.show()

Adjusting Title Position

You can customize the title position and appearance using additional parameters ?

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

df = pd.DataFrame(np.random.random((5, 4)),
                  columns=["Feature A", "Feature B", "Feature C", "Feature D"])

pp = sns.pairplot(df, height=2.0)

# Add title with custom positioning
pp.fig.suptitle("Data Relationships Analysis", 
                 fontsize=16, 
                 y=1.02)  # y=1.02 moves title slightly up

plt.tight_layout()
plt.show()

Key Parameters

Conclusion

Use fig.suptitle() on pairplot or PairGrid objects to add titles. Adjust positioning with the y parameter and use plt.tight_layout() to prevent overlap with subplots.
