How to adjust 'tick frequency' in Matplotlib for string X-axis?

To adjust tick frequency for X-axis, we can take the following steps −

Set the figure size and adjust the padding between and around the subplots.
Initialize a variable, N, for number of sample data points.
Create x and y data points using numpy.
Plot x and y data points using plot() method.
Initialize a variable freq_x to adjust the frequency of the xticks.
Use xticks() method to set the xticks.
To display the figure, use show() method.

Example

import matplotlib.pyplot as plt
import numpy as np

plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True

N = 10

x = np.random.randint(low=0, high=N, size=N)
y = np.random.randint(low=0, high=N, size=N)

plt.plot(x, y, color='red')

freq_x = 3

plt.xticks(np.arange(0, N, freq_x))

plt.show()
