matplotlib histogram plot 'density' argument not working

Question

I try running the following code

import numpy as np
import matplotlib.pyplot as plt

x = np.random.randn(1000)
plt.hist(x, bins=50, density=True)
plt.show()

And I get the following error message:

AttributeError: Unknown property density

What's wrong?

What version of matplotlib are you using? Versions < 2 don't have the density argument for hist — DavidG

What is the Python version and matplotlib version you are using?

Older versions of matplotlib (e.g. 1.3.1) don't have the density parameter, but instead have the normed parameter. This is probably why you are getting the AttributeError.

To check the matplotlib version, you can simply do:

python -m pip list

Versions of matplotlib above 2.0 all have the density parameter.
