Technical requirements

The main plotting package for Python is Matplotlib, which can be installed using your favorite package manager, such as pip:

python3.10 -m pip install matplotlib

This will install the most recent version of Matplotlib, which, at the time of writing this book, is version 3.5.2.

Matplotlib contains numerous sub-packages, but the main user interface (UI) is the matplotlib.pyplot package, which, by convention, is imported under the plt alias. This is achieved using the following import statement:

import matplotlib.pyplot as plt

Many of the recipes in this chapter also require NumPy, which, as usual, is imported under the np alias.

The code for this chapter can be found in the Chapter 02 folder of the GitHub repository at https://github.com/PacktPublishing/Applying-Math-with-Python-2nd-Edition/tree/main/Chapter%2002.
