How to Add Titles to Plots in Matplotlib

You can use the following syntax to add a title to a plot in Matplotlib:

plt.title('My Title')

The following examples show how to use this syntax in practice.

Example 1: Add Title to Plot

The following code shows how to add a title to a plot in Matplotlib:

import matplotlib.pyplot as plt

#define x and y
x = [1, 4, 10]
y = [5, 11, 27]

#create plot of x and y
plt.plot(x, y)

#add title
plt.title('My Title')

Note that you can also use the fontsize and loc arguments to specify the font size and location of the title, respectively:

plt.title('My Title', fontsize=30, loc='left')

Example 2: Add Title to Subplots

The following code shows how to use the set_title() function to specify titles for individual subplots in Matplotlib:

import matplotlib.pyplot as plt

#define subplots
fig, ax = plt.subplots(2, 2)
fig.tight_layout()

#define subplot titles
ax[0, 0].set_title('First Subplot')
ax[0, 1].set_title('Second Subplot')
ax[1, 0].set_title('Third Subplot')
ax[1, 1].set_title('Fourth Subplot')
