How to make several legend keys to the same entry in Matplotlib?
To make several legend keys to the same entry in Matplotlib, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Plot line1 and line2 using plot() method.
- Use legend() method to place a legend over the plot with numpoints=1
- To display the figure, use show() method.
Example
import matplotlib.pyplot as plt
from matplotlib.legend_handler import HandlerTuple
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
p1, = plt.plot([1, 2.5, 3], 'r-d')
p2, = plt.plot([3, 2, 1], 'k-o')
l = plt.legend([(p1, p2)], ['Two keys'], numpoints=1, handler_map={tuple: andlerTuple(ndivide=None)})
plt.show()Output
