Histogram Vs Box Plot using Matplotlib

Both box plot and histogram are used for data visualization and analyzing the central tendency in data. Therefore, we are comparing both so that we can find which is a good data visualization technique.

Examples

Python program for histogram vs box plot using matplotlib

import numpy as np
import matplotlib.pyplot as plt

# Generating Data
spread = np.random.rand(65) * 82
center = np.ones(36) * 50
flier_high = np.random.rand(12) * 100 + 100
flier_low = np.random.rand(10) * -100
data = np.concatenate((spread, center, flier_high, flier_low))

plt.figure()
plt.title('Horizontal Histogram')
plt.hist(data)
plt.ylabel('Variation')
plt.grid()

plt.figure()
plt.title('Horizontal Histogram')
plt.boxplot(data)
plt.ylabel('Variation')
plt.grid()

plt.figure()
plt.subplot(121)
plt.title('Horizontal Histogram')
plt.hist(data)
plt.ylabel('Variation')
plt.grid()

plt.subplot(122)
plt.title('Horizontal Histogram')
plt.boxplot(data)
plt.ylabel('Variation')
plt.grid()

Output:

Output is as Figure
