Matplotlib Pyplot

This lesson is part of Python · All levels

Summary

The pyplot module works with a state-based pattern: each function called influences the active figure that is being opened. The main function plt.plot() draws a line graph from two lists of values, and can be called many times to add several lines in a single figure. In addition to drawing, the pyplot also provides the function of adding a title and an axis label to make the graphics readable. Understanding these patterns makes the layout of the graph systematic and easy to clean.

Pyplot manages the active figure automatically (state-based)
Plt.plot(x, y) Draw a line based on the value pair
Several plt.plot() in a block produce several lines
The headline and axis labels are added to make the graphics easy to read
