How to Fix Overlapping or Cut Off Labels in Matplotlib Plots?

How to Resolve Padding Issues with Overlapping or Cutoff Labels in Matplotlib

Issue:

When drawing plots with labels that contain complex expressions or line breaks, the bottom portion of x-axis labels may get cut off.

Solution:

Adjusting Padding

To accommodate the taller labels, you can manually adjust the padding using subplots_adjust(). Specify a larger value for the bottom parameter to create more space below the x-axis.

import matplotlib.pyplot as plt

plt.gcf().subplots_adjust(bottom=0.15)  # Adjust the bottom padding

# Alternatively, use plt.subplots_adjust() without .gcf()
plt.subplots_adjust(bottom=0.15)

Tight Layout

For a more automated solution, use the tight_layout() function. This dynamically optimizes the layout of the plot to prevent overlaps between labels and the axes.

fig, axes = plt.subplots(ncols=2, nrows=2, figsize=(8, 6))
axes = axes.flatten()

for ax in axes:
    ax.set_ylabel(r'$\ln\left(\frac{x_a-x_b}{x_a-x_c}\right)$')
    ax.set_xlabel(r'$\ln\left(\frac{x_a-x_d}{x_a-x_e}\right)$')

plt.tight_layout()
plt.show()
