Bar plot hover shows incorrect bar length when base is used

Hello,

I tried making something like a Gantt chart and use the Bar plot type for that. It seems the hover effect is mixing up the columns somehow. Here is a minimal reproduction:

import pandas as pd
import plotly.express as px

gantt = []
gantt.append(dict(Begin=0, End=1, Word='Foo'))
gantt.append(dict(Begin=2, End=5, Word='Bar'))
gantt_df = pd.DataFrame(gantt)
gantt_df['Duration'] = (gantt_df['End'] - gantt_df['Begin'])

fig = px.bar(gantt_df, base="Begin", y="Duration", x="Word")
fig.show()

Here is the result:

Things of note:

• The position and size of the bars is correct
• The "Begin" annotation in the hover is correct
• The "Duration" annotation shows the value of the "End" column, which is not correct. I would expect "End=5" or "Duration=3" but not "Duration=5"

Examining the pandas dataframe itself shows that the data itself is correct:

This is my version according to conda:
plotly 5.23.0 pyhd8ed1ab_0 conda-forge

Thank you for providing this great library for free and I hope that you find my report helpful.

まず、issue にある pandas と plotly.express の最小再現コードを plotly 5.23.0 で実行し、描画されたバーの hover フィールドを dataframe 内の Begin、End、Duration と比較します。バーの位置が正しいままで、hover に End ではなく期待される Duration の値が表示されれば、作業は完了です。
