How to Add Text Inside the Plot in Matplotlib

We use the matplotlib.pyplot.text() method to add text inside a plot in Matplotlib.

matplotlib.pyplot.text() Method

matplotlib.pyplot.text() adds text to the figure or to the axes in Matplotlib.

Syntax

matplotlib.pyplot.text(x, y, s, fontdict=None, **kwargs)

x and y represent the coordinates where we need to place the text, and s is the text’s content that needs to be added. The fontdict parameter is a dictionary used to set the properties of the text.

Examples: Add Text Inside the Plot Matplotlib Using matplotlib.pyplot.text() Method

import matplotlib.pyplot as plt

plt.text(0.55, 0.55, "Hello World!", fontsize=20, color="green")
plt.show()

Output:

It will simply put the text inside the plot at position (0.55, 0.55) with font size as 20 and green color. By default, the limit of both the X-axis and Y-axis ranges from 0 to 1, so we won’t be able to see the text out of this range.

To put the text at any position with the X-axis or Y-axis out of the range (0,1), we need to change the limit of the respective axis.

import matplotlib.pyplot as plt

plt.text(4, 6, "Hello World!", fontsize=20, color="green")
plt.xlim([0, 10])
plt.ylim([0, 10])

plt.show()

Output:

We can also add various styling to the text using the **kwargs.

import matplotlib.pyplot as plt

plt.text(
    5,
    5,
    "Hello World!",
    fontsize=20,
    color="red",
    verticalalignment="top",
    horizontalalignment="center",
    bbox={"facecolor": "grey", "pad": 10},
)

plt.xlim([0, 10])
plt.ylim([0, 10])
plt.show()

Output:
