import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
weights = [78, 72, 69, 81, 63, 67, 65, 75, 79, 74, 71, 83, 71, 79, 80, 69]
plt.figure(figsize = (10, 5))
n, edges, p = plt.hist(weights, bins = 40, histtype = 'step')
m = 0.5 * (edges[1:] + edges[:-1])
m = m.tolist()
l = len(m)
m.insert(0, m[0] - 10)
m.append(m[l-1] + 10)
n = n.tolist()
n.insert(0, 0)
n.append(0)
plt.plot(m, n, '-^')
plt.show()

Create an ndarray containing 16 values and then plot this array along with dataset of previous question in same histogram, horizontal histograms.
Out of above plotted histograms, which ones can be used for creating frequency polygons ? Can you draw frequency polygons from all the above histograms ?
