How to add a title to a Matplotlib legend?
• Last Updated : 24 Jan, 2021

Prerequisites: Matplotlib

In this article, we will see how can we can add a title to a legend in our graph using matplotlib, Here we will take two different examples to showcase our graph.

Approach:

• Import required module.
• Create data.
• Add a title to a legend.
• Normally plot the data.
• Display plot.

Below is the Implementation:

Example 1:

In this example, we will draw different lines with the help of matplotlib and Use the title argument to plt.legend() to specify the legend title.

## Python3

 `# importing package``import` `matplotlib.pyplot as plt``import` `numpy as np`` ` `# create data``X ``=` `[``1``, ``2``, ``3``, ``4``, ``5``]`` ` `# plot lines``plt.plot(X, np.sin(X), label ``=` `"Curve-1"``)``plt.plot(X, np.cos(X), label ``=` `"Curve-2"``)`` ` `# Add a title to a legend``plt.legend(title ``=` `"Legend Title"``)``plt.title(``"Line Graph - Geeksforgeeks"``)`` ` `plt.show()`

Output: Example 2:

In this example, we will draw a Bar Graph with the help of matplotlib and Use the title argument to plt.legend() to specify the legend title.

## Python3

 `# importing package``import` `matplotlib.pyplot as plt`` ` `# sample code ``plt.bar([``1``, ``2``, ``3``], [``16``, ``4``, ``1``], ``        ``color ``=``'yellow'``,``        ``label ``=` `'Label 2'``) `` ` `plt.bar([``4``, ``5``], [``2``, ``4``], ``        ``label ``=` `'Label 1'``)`` ` `# Add a title to a legend``plt.legend(title ``=` `"Variation Rate"``)`` ` `plt.title(``"Line Graph - Geeksforgeeks"``)`` ` `plt.show()`
