How do I change the axis tick font in a Matplotlib plot when rendering using LaTeX?

To change the axis tick font in matplotlib when rendering using LaTeX, we can take the following Steps −

  • Create x and y data points using numpy.

  • Using subplot() method, add a subplot to the current figure.

  • Set x and y ticks with data points x and y using set_xticks and set_yticks methods, respectively.

  • Plot x and y using plot() method with color=red.

  • To set bold font weight, we can use LaTeX representation.

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


import numpy as np
import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
x = np.array([1, 2, 3, 4])
y = np.exp(x)

ax1 = plt.subplot()
ax1.plot(x, y, c="red")
ax1.set_xticklabels(["$\bf{one}$", "$\bf{two}$", "$\bf{three}$", "$\bf{four}$"], rotation=45)
ax1.set_yticklabels(["$\bf{:.2f}$".format(y[0]), "$\bf{:.2f}$".format(y[1]),
   "$\bf{:.2f}$".format(y[2]), "$\bf{:.2f}$".format(y[3])], rotation=45)
