python - Share x axis between matplotlib and seaborn

Python - Share x axis between matplotlib and seaborn

To share the x-axis between matplotlib and seaborn plots in Python, you can use the subplots() function from matplotlib to create a figure with multiple subplots. This approach allows you to plot with seaborn on one subplot and then add another plot directly on the same x-axis using matplotlib. Here's a step-by-step guide to achieve this:

Example Scenario

Assume you have data that you want to visualize with both seaborn and matplotlib, sharing the same x-axis.

Example Data

Let's create some sample data to demonstrate the approach:

import matplotlib.pyplot as plt import seaborn as sns import numpy as np # Sample data x = np.linspace(0, 10, 100) y1 = np.sin(x) y2 = np.cos(x)

Plotting with Seaborn and Matplotlib

  1. Create Subplots: Use matplotlib.pyplot.subplots() to create a figure with multiple subplots.

  2. Plot with Seaborn: Plot one dataset using seaborn on the first subplot.

  3. Plot with Matplotlib: Plot another dataset directly using matplotlib on the same x-axis (sharing).

# Create subplots with shared x-axis fig, ax = plt.subplots() # Plot with seaborn on the first subplot sns.lineplot(x=x, y=y1, ax=ax) # Plot with matplotlib on the same x-axis ax.plot(x, y2, color='red') # You can customize the plot as needed # Customize labels, title, etc. ax.set_xlabel('X-axis') ax.set_ylabel('Y-axis') ax.set_title('Seaborn and Matplotlib Sharing X-axis') # Show plot plt.show()

Explanation

  • plt.subplots(): Creates a figure (fig) and a single subplot (ax). You can specify more rows and columns if needed (plt.subplots(nrows, ncols)).

  • sns.lineplot(): Plots data using seaborn on the subplot (ax).

  • ax.plot(): Plots data using matplotlib directly on the same subplot (ax). This ensures the x-axis is shared between both plots.

  • Customization: You can customize the plot further by adding labels (set_xlabel(), set_ylabel()) and a title (set_title()).

  • plt.show(): Displays the plot.

Notes

  • Seaborn is built on top of matplotlib, so they integrate well together. You can seamlessly use seaborn for its specialized plots and still customize or add additional plots using matplotlib on the same figure.

  • Ensure that the data and plot settings (like colors, labels, and titles) are adjusted according to your specific requirements and data characteristics.

By following these steps, you can effectively share the x-axis between seaborn and matplotlib plots in Python, allowing for integrated visualization of data using both libraries. Adjust the code and data to fit your specific use case and visualization needs.
