Styling a part of label in legend in Matplotlib

To style a part of label in legend, we can take the following steps −

• Create data point for x using numpy.

• Plot a sine curve using np.sin(x) with a text label.

• Plot a cosine curve using np.cos(x) with a text label.

• To place the legend on the plot, use legend() method.

• To display the figure, use show() method.

Example

import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.00, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(-1, 1, 10) plt.plot(x, np.sin(x), label="This is $\it{a\ sine\ curve}$") plt.plot(x, np.cos(x), label="This is $\bf{a\ cosine\ curve}$") plt.legend(loc='lower right') plt.show()
