Write a program to create a horizontal bar chart from two data sequences

Q. Write a program to create a horizontal bar chart from two data sequences as given below:

means [20, 35, 30, 35, 27]
stds = [2, 3, 4, 1, 2]

Make sure to show legends.

Answer :-

import matplotlib.pyplot as plt
import numpy as np

means = [20, 35, 30, 35, 27]
stds = [2, 3, 4, 1, 2]

indx = np.arange (len (means))
plt.barh(indx, means, color ='cyan', label = 'means')
plt.barh(indx +0.25, stds, color = 'olive', label = "stds")

plt.legend()
plt.show()

Output :-
