Plot legend python

A legend is an area describing the elements of the graph. In this article, we will learn about the Matplotlib Legends.

The elements to be added to the legend are automatically determined, when you do not pass in any extra arguments. In this case, the labels are taken from the artist. A string starting with an underscore is the default label for all artists, so calling Axes. For full control of which artists have a legend entry, it is possible to pass an iterable of legend artists followed by an iterable of legend labels respectively:.

A Legend in a Graph is considered a guide to understanding the graph. When a graph has more than one output, the outputs are usually classified by visually differentiable features such as colors, lines, etc. A legend helps the viewer understand what the graph is implying. It helps users classify data, help select features that are important to model, and chart out relations between different features. Graphical visualization helps users to remove redundant features, train models on relationships deduced from the graphs, analyze outliers and remove them. In Python, the PyPlot module of the Matplotlib library does the task.
