Research direction

Start with the MWE linked in pint-pandas issue #249 and reproduce the reported AttributeError through the Plotly Pandas dataframe backend. Trace how Pint scalars are recognized during plotting, then verify that the MWE produces figures without the error for unit-bearing data.

Written by the indexing model from the issue text.

Description

feature P3

I love the figures generated with plotly. I want to use it as the backend for a Pandas dataframe that has units of measurement using (Pint). Unfortunately, these plots fail with the error:

AttributeError: 'float' object has no attribute 'tolist'

It seems that the issue is that Plotly is not recognizing Pint scalars as scalars. A MWE example is given on the following pint-pandas issue.

Thanks.
