How to plot a non-square Seaborn jointplot or JointGrid? (Matplotlib)

Seaborn's jointplot() creates square plots by default, but you can create non-square (rectangular) plots by adjusting the figure dimensions using set_figwidth() and set_figheight() methods.

Basic Non-Square Jointplot

Here's how to create a rectangular jointplot by modifying the figure dimensions ?

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

# Generate sample data
np.random.seed(42)
x_data = np.random.randn(1000)
y_data = 0.2 * np.random.randn(1000) + 0.5

# Create DataFrame
df = pd.DataFrame({'x': x_data, 'y': y_data})

# Create jointplot
jp = sns.jointplot(x="x", y="y", data=df, height=4, 
                   joint_kws={'color': 'blue'})

# Make it non-square by setting custom width and height
jp.fig.set_figwidth(8)
jp.fig.set_figheight(4)

plt.show()

Using JointGrid for More Control

For advanced customization, use JointGrid directly ?

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

# Generate sample data
np.random.seed(42)
x_data = np.random.randn(500)
y_data = 0.3 * x_data + np.random.randn(500) * 0.5

df = pd.DataFrame({'x': x_data, 'y': y_data})

# Create JointGrid with custom aspect ratio
grid = sns.JointGrid(data=df, x="x", y="y", height=4)

# Set custom figure dimensions
grid.fig.set_figwidth(10)
grid.fig.set_figheight(5)

# Plot the data
grid.plot_joint(sns.scatterplot, alpha=0.6, color='green')
grid.plot_marginals(sns.histplot, kde=True, alpha=0.7)

plt.show()

Different Aspect Ratios

You can create various rectangular shapes by adjusting the width-to-height ratio ?

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

# Generate correlated data
np.random.seed(123)
x_data = np.random.normal(0, 1, 800)
y_data = 0.6 * x_data + np.random.normal(0, 0.8, 800)

df = pd.DataFrame({'x': x_data, 'y': y_data})

# Create wide horizontal plot
jp = sns.jointplot(x="x", y="y", data=df, kind="reg", height=3)
jp.fig.set_figwidth(12)  # Wide
jp.fig.set_figheight(4)  # Short

plt.suptitle("Wide Horizontal Jointplot", y=1.02)
plt.show()

Key Parameters

Conclusion

Use set_figwidth() and set_figheight() on the jointplot's figure object to create non-square plots. JointGrid provides more control for complex customizations with rectangular aspect ratios.
