histogram() got an unexpected keyword argument 'legend' with pandas backend

pandas version 1.1.0
plotly version 4.9.0

The following will raise histogram() got an unexpected keyword argument 'legend' :

import pandas as pd
pd.options.plotting.backend = "plotly"
df = pd.DataFrame()
df.hist()

I suggest to add legend in the skip list:

plotly.py/packages/python/plotly/plotly/__init__.py

Line 161 in dc9c5fd

skip += ["ax", "sharex", "sharey", "figsize", "layout", "bins"]

Thanks for the bug report and suggested fix! Should be in the next version :)
