How to display all label values in Matplotlib?

To display all label values, we can use set_xticklabels() and set_yticklabels() methods.

Steps

Create a list of numbers (x) that can be used to tick the axes.
Get the axis using subplot() that helps to add a subplot to the current figure.
Set the ticks on X and Y axes using set_xticks and set_yticks methods respectively and list x (from step 1).
Set tick labels with label lists (["one", "two", "three", "four"]) and rotation of 45 using set_xticklabels() and set_yticklabels().
To add space between axes and tick labels, we can use tick_params() method with pad argument that helps to add space. Argument direction (in) helps to put ticks inside the axes, and axis (both), parameters to be applied on both the axes.
To show the figure, use plt.show() method.

Example

import matplotlib.pyplot as plt
plt.rcParams["figure.figsize"] = [7.00, 3.50]
plt.rcParams["figure.autolayout"] = True
x = [1, 2, 3, 4]
ax1 = plt.subplot()
ax1.set_xticks(x)
ax1.set_yticks(x)
ax1.set_xticklabels(["one", "two", "three", "four"], rotation=45)
ax1.set_yticklabels(["one", "two", "three", "four"], rotation=45)
ax1.tick_params(axis="both", direction="in", pad=15)
plt.show()
