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 packageimport matplotlib.pyplot as pltimport numpy as np  # create dataX = [1, 2, 3, 4, 5]  # plot linesplt.plot(X, np.sin(X), label = "Curve-1")plt.plot(X, np.cos(X), label = "Curve-2")  # Add a title to a legendplt.legend(title = "Legend Title")plt.title("Line Graph - GeeksforLazyroar")  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 packageimport 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 legendplt.legend(title = "Variation Rate")  plt.title("Line Graph - GeeksforLazyroar")  plt.show() |
Output:
