 .. note::
     When we create the histograms in this example, we use the argument ``storage=bh.storage.Weight()``.
-    This is because the functions in ``plothist`` assume histograms with a storage that supports weighted data, where the variance of each bin is tracked (more details `here < https://boost-histogram.readthedocs.io/en/latest/user-guide/storage.html#weight>`_ and `there <https://boost-histogram.readthedocs.io/en/latest/api/boost_histogram.html#boost_histogram._internal.hist.Histogram.variances>`_).

     When creating histograms with regular or variable axes with the function :func:`make_hist() <plothist.histogramming.make_hist>`, as in most of the previous examples, the storage is automatically set to ``bh.storage.Weight()``, so the user does not have to worry about it.
