#348 Histogram plot with python

In this example, plot ticks coincide with bin edges.

import numpy as np
import matplotlib.pyplot as plt
data = np.random.default_rng(1234).rayleigh(1,40)
counts, edges, bars = plt.hist(data, edgecolor="red",bins=[0, 1, 2, 3, 4])
plt.bar_label(bars)
plt.xticks(edges)
plt.savefig('ex348.png', dpi=72)
plt.show()
