How to Prevent Labels from Being Cut Off in Matplotlib Plots?

Adjusting Padding with Cutoff or Overlapping Labels

Problem

In matplotlib plots, labels can sometimes be cut off due to overlapping with the axis title or figure frame. This issue can be particularly noticeable for "tall" labels, such as mathematical formulas or multi-line text.

Solution

To adjust the padding and make room for the labels, use plt.gcf().subplots_adjust() or plt.subplots_adjust(). This function takes a keyword argument bottom that specifies the amount of space to add below the plot. A larger value will result in more padding.

For example:

import matplotlib.pyplot as plt

plt.gcf().subplots_adjust(bottom=0.15)

# or, without .gcf

plt.subplots_adjust(bottom=0.15)

Alternate Option

Recently, matplotlib added a plt.tight_layout() function. This function automatically adjusts the padding around the plot to accommodate the labels, providing a more optimal layout.

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()
