Rotating the axis labels can be helpful when the labels are long and overlap with each other, making it difficult to read. In Python, you can rotate the x-axis or y-axis labels using the xticks() or yticks() functions in Matplotlib.

Here's an example of rotating the x-axis labels by 45 degrees using xticks():

import matplotlib.pyplot as plt

import numpy as np

# Generate some random data

x = np.arange(10)

y = np.random.randint(1, 10, size=10)

# Create a bar plot

plt.bar(x, y)

# Rotate the x-axis labels by 45 degrees

plt.xticks(rotation=45)

# Set the title and axis labels

plt.title('Bar Plot with Rotated Labels')

plt.xlabel('Categories') plt.ylabel('Values') 

# Show the plot

plt.show()

In this example, we generate 10 random values for the y-axis and create a bar plot using plt.bar(). We then use plt.xticks(rotation=45) to rotate the x-axis labels by 45 degrees. Finally, we set the title and axis labels using plt.title(), plt.xlabel(), and plt.ylabel(), and display the plot using plt.show().

Similarly, you can rotate the y-axis labels by using yticks() function and setting the rotation parameter.
