Write a program to plot this data on a cumulative bar-stacked horizontal histogram

Q. Prof Awasthi is doing some research in the field of Environment. For some plotting purposes, he has generated some data as :

mu = 100
sigma = 15
x = mu + sigma * numpy.random.randn(10000)
y = mu + 30 * np.random.randn (10000)

Write a program to plot this data on a cumulative bar-stacked horizontal histogram with both x and y.

Answer :-

import numpy as np
import matplotlib.pyplot as plt

mu = 100
sigma = 15
x = mu + sigma * np.random.randn (10000)
y = mu + 30 * np.random.randn (10000)

plt.hist([x,y], bins = 100, histtype = 'barstacked', cumulative = True)
plt.title('Research data Histogram')
plt.show()

Output:-
