When hist() is passed irregular bins with normed=True, the output is different between matplotlib 2.0 and 2.1. Here is a test script to reproduce the issue:
# Python 3.6
import matplotlib.pyplot as plt
import matplotlib
import numpy as np
rng = np.random.RandomState(829)
t = np.concatenate([rng.randn(100),
2 + 0.1 * rng.randn(100),
5 + 3 * rng.randn(100)])
plt.hist(t, bins=[-5, -3, -2, -1, -0.5, 0, 2, 4, 5, 10], normed=True)
plt.title(f'matplotlib v{matplotlib.__version__}')
plt.savefig(f'hist-{matplotlib.__version__}.png')
plt.show()hist-2.0.2.png:
