Thank you for fixing the style of the docstring @erichxchen.
I think think needs a bit more of work, as this doesn't seem very accurate. In general this will return the matplotlib object representing the histogram. This is what we should say first. Then, I'm not sure if an array is returned when by is used. Can you do some tests and make sure that what we provide here is relevant and correct please?

Sure, I will be working on this
