How to Set Tick Label in Scientific Notation in Matplotlib

This post will teach you about using Matplotlib ticklabel_format() to display ticks label in scientific notation.

Matplotlib Tick Label in Scientific Notation

Too large or too few numbers readily stated in decimal form can be expressed using scientific notation.

First, import the necessary library:

import matplotlib.pyplot as plt

Provide the values along with the x and y axes:

x_val = [1000000, 2000000, 3000000]
y_val = [1, 2, 3]

Let’s plot these numbers using Matplotlib:

plt.plot(x_val, y_val)

plt.ticklabel_format(axis="x", style="sci", scilimits=(0, 0))

Output:

To plot, we use the ticklabel_format() function, which takes the parameter axes and style=sci, which denotes the scientific notation.
