Wrapping long y labels in matplotlib tight layout using setp

Wrapping long y labels in matplotlib tight layout using setp

In Matplotlib, you can wrap long y-axis labels when using tight_layout by adjusting the ytick.labelsize and ytick.rotation properties of the axes. Here's how you can do it:

import matplotlib.pyplot as plt # Sample data and long y-axis labels x = [1, 2, 3, 4, 5] y = [1000000, 2000000, 3000000, 4000000, 5000000] y_labels = ['Label 1', 'A very long label 2', 'Label 3', 'Another long label 4', 'Label 5'] # Create a figure and axis fig, ax = plt.subplots() # Plot your data ax.plot(x, y) # Set y-axis labels and adjust properties for wrapping ax.set_yticklabels(y_labels, fontsize=10) # Set font size as needed ax.tick_params(axis='y', labelrotation=0) # Set the desired rotation angle (0 degrees for no rotation) # Adjust layout plt.tight_layout() # Show the plot plt.show()

In this example:

  1. We create a sample plot with a list of x values, y values, and long y_labels.

  2. We set the y-axis labels using ax.set_yticklabels(y_labels, fontsize=10) and adjust the font size as needed.

  3. We use ax.tick_params(axis='y', labelrotation=0) to set the rotation angle of the y-axis labels. A rotation angle of 0 degrees means no rotation, which effectively wraps the long labels.

  4. Finally, we call plt.tight_layout() to ensure that the plot layout is adjusted to accommodate the wrapped labels without overlapping.

This will result in a plot with wrapped long y-axis labels while using tight_layout to adjust the layout appropriately. You can adjust the font size and rotation angle to fit your specific requirements.
