To modify a Matplotlib legend after it has been created, we can have multiple methods to modify the created legend.
- Set the figure size and adjust the padding between and around the subplots.
- Plot a line using plot() method, with two lists and a label.
- Use legend() method to place a legend over the plot.
- To modify the matplotlib legend, use set_title() method.
- To display the figure, use show() method.
Example
from matplotlib import pyplot as plt
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
plt.plot([1, 3, 4, 5, 2, 1], [3, 4, 1, 3, 0, 1],
label="line plot", color='red', lw=0.5)
leg = plt.legend(loc="upper right")
leg.set_title("Title")
plt.show()Output
