How to set font size of Matplotlib axis Legend?

How to set font size of Matplotlib axis Legend?

You can set the font size of the legend in a Matplotlib plot by using the fontsize parameter of the legend function. Here's how you can do it:

import matplotlib.pyplot as plt # Sample data x = [1, 2, 3, 4, 5] y = [2, 4, 6, 8, 10] # Create a plot plt.plot(x, y, label='Data') # Add a legend and set the font size plt.legend(fontsize=12) # Adjust the fontsize to your desired value # Show the plot plt.show()

In the example above, we first create a plot and then add a legend with plt.legend(). Inside the legend() function, you can set the fontsize parameter to the desired font size. Adjust the value of fontsize to your preferred font size. This will change the font size of the legend text.

You can also set the font size for the legend title (if present) using the title_fontsize parameter:

plt.legend(fontsize=12, title='Legend Title', title_fontsize=14)

In this case, we set the font size for both the legend text and the legend title.
