MatplotlibServer Side ProgrammingProgramming

To change the text color of font in the legend in matplotlib, we can take the following steps−

  • Create x and y data points using numpy.
  • Plot x and y using plot() method, where color of line is red and label is "y=exp(x)".
  • To place the legend, use legend() method with location of the legend and store the returned value to set the color of the text.
  • To set the color of the text, use set_color() method with green color.
  • 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(-2, 2, 100)
y = np.exp(x)
plt.plot(x, y, label="y=exp(x)", c='red')
leg = plt.legend(loc='upper left')
for text in leg.get_texts():
text.set_color("green")
plt.show()
