Pyplot Basics

pyplot contains a simpler interface for creating visualizations that allow the users to plot the data without explicitly configuring the Figure and Axes themselves. They are automatically configured to achieve the desired output. It is handy to use the alias plt to reference the imported submodule, as follows:

import matplotlib.pyplot as plt

The following sections describe some of the common operations that are performed when using pyplot.

By default, the Figure has a width of 6.4 inches and a height of 4.8 inches with a dpi (dots per inch) of 100. To change the default values of the Figure, we can use the parameters figsize and dpi.
