Python code for broken bar graph using matplotlib

# Data Visualization using Python
# Broken Bar Graph

import numpy as np
import matplotlib.pyplot as plt

N = 8
x = np.array([1,2,3,4,5,6,7,9])

xx = np.array(['a','b','c','d','e','f','g','u'])
y = np.random.rand(N)*5
yy = 5 + np.random.rand(N)

# a normal bar plot with default features
plt.bar(x, y, bottom=yy  )
plt.xlabel('Numbers')
plt.ylabel('Values')
plt.title('Normal broken bar Plot')
plt.show()

# a bar plot with green collour
plt.figure()
plt.bar(x, y, color='yellow', bottom=yy)
plt.xlabel('Numbers')
plt.ylabel('Values')
plt.title('Broken Bar with Different Colour')
plt.show()

# a bar plot with string points
plt.figure()
plt.bar(xx, y, color='red', bottom=yy)
plt.xlabel('Numbers')
plt.ylabel('Values')
plt.title('Broken Bar Graph with String')
plt.show()

# A combined bar Plot
plt.figure()
plt.bar(np.arange(26), np.random.randint(0,50,26), alpha = 0.6, bottom=np.random.randint(0,50,26))
plt.xlabel('Numbers')
plt.ylabel('Values')
plt.title('Broken Bar : Random Plot')
plt.show()
