How to write your own LaTeX preamble in Matplotlib?

To write your own LaTeX preamble in Matplotlib, we can take the following steps −

• Set the figure size and adjust the padding between and around the subplots.
• Create x and y random data points using numpy.
• Plot x and y data points using plot() method. Use LaTex formatting for the label.label="$y=e^{x}$"
• Place a legend on the figure using legend() method.
• To display the figure, use show() method.

Example

import numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(-10, 10, 100) y = np.exp(x) plt.plot(x, y, color='red', label="$y=e^{x}$") plt.legend(loc='upper right') plt.show()
