描述
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.

调研方向
首先使用 plotly 5.23.0 运行 issue 中 pandas 和 plotly.express 的最小复现,并将渲染后的条形图 hover 字段与 dataframe 中的 Begin、End 和 Duration 进行比较。当条形图的位置保持正确,并且 hover 显示预期的 Duration 值而不是 End 时,工作就完成了。
