How to Customize Tick Label Appearance in Matplotlib: Font Size and Rotation?

How to Modify Tick Label Appearance in Matplotlib

In matplotlib, customizing the appearance of tick labels enhances the readability and aesthetics of visualizations. Here's a detailed guide to adjusting the font size and rotation of tick labels:

Changing Font Size

To modify the font size of tick labels, use the labelsize argument within the tick_params() method. Here's an example:

<code class="python">import matplotlib.pyplot as plt

# Create a figure and axis
fig, ax = plt.subplots()

# Change the font size of major (x-axis) and minor (y-axis) tick labels
ax.tick_params(axis='x', which='major', labelsize=10)
ax.tick_params(axis='y', which='minor', labelsize=8)

# Show the plot
plt.show()</code>

Rotating Tick Labels

To rotate tick labels from horizontal to vertical, use the rotation argument within the tick_params() method. A rotation value of 90 degrees will orient the labels vertically.

<code class="python">import matplotlib.pyplot as plt

# Create a figure and axis
fig, ax = plt.subplots()

# Rotate the x-axis tick labels to 90 degrees
ax.tick_params(axis='x', rotation=90)

# Show the plot
plt.show()</code>

Note that not all tick labels may fit vertically, especially with limited space. In such cases, consider adjusting the spacing or axis limits to accommodate the rotated labels.
