• Set x and y ticks using set_xticks() and set_yticks() method.
• 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 ax = plt.gca() data = np.random.rand(6, 6) ax.imshow(data) # Set xticks and yticks ax.set_xticks([1, 2, 3, 4, 5]) ax.set_yticks([1, 2, 3, 4, 5]) plt.show()
