Hello, The documentation for hist seems to indicate that you should be able to send a list of values through the 'weights' parameter in axes.hist, and this worked in previous versions. In 1.0, however, this produces an error. I've attached a diff (also pasted below) that I believe produces the expected behavior.
It can be tested with: plt.hist([1,2,3], weights=[1,2,3]) The above fails in the development version, but works with the diff. Could someone add this fix?
