Changing Tick Label Font Size and Rotation in Matplotlib

In Matplotlib, customizing plot elements, such as tick labels, allows for enhanced visualization and detailed analysis. This guide explores how to adjust the font size of tick labels and rotate them from horizontal to vertical.

Adjusting Font Size

The ax1.set_xticklabels() method is not the recommended approach for changing the font size of tick labels. Instead, consider using the tick_params() function. It provides more flexibility and control over both major and minor tick label properties.

<code class="python">import matplotlib.pyplot as plt
# Prepare the plot
fig, ax = plt.subplots()

# Adjust font size of major tick labels
ax.tick_params(axis='both', which='major', labelsize=10)

# Adjust font size of minor tick labels
ax.tick_params(axis='both', which='minor', labelsize=8)</code>

Rotating Tick Labels

To rotate tick labels from horizontal to vertical, the rotation keyword argument can be指定 in the tick_params() function.

<code class="python"># Rotate tick labels by 90 degrees
ax.tick_params(axis='both', rotation=90)</code>

By combining these methods, you can easily fine-tune the appearance of your tick labels, improving readability and enhancing the overall presentation of your graphs.
