如何在同一图形的不同轨迹上添加 hover_data

Question

fig = go.Figure()


fig.add_trace(
  go.Scatter(x=alldates, y=countriesData[0]["ToxPi Score"], name="Suffolk")
)
fig.add_trace(
  go.Scatter(x=alldates, y=countriesData[1]["ToxPi Score"], name="Plymouth")
)
fig.add_trace(
  go.Scatter(x=alldates, y=countriesData[2]["ToxPi Score"], name="Bristol")
)
fig.add_trace(
  go.Scatter(x=alldates, y=countriesData[3]["ToxPi Score"], name="Norfolk")
)
fig.add_trace(
  go.Scatter(x=alldates, y=countriesData[4]["ToxPi Score"], name="Middlesex")
)
fig.add_trace(
  go.Scatter(x=alldates, y=countriesData[5]["ToxPi Score"], name="Worcester")
)
fig.add_trace(
  go.Scatter(x=alldates, y=countriesData[6]["ToxPi Score"], name="Barnstable")
)
fig.add_trace(
  go.Scatter(x=alldates, y=countriesData[7]["ToxPi Score"], name="Franklin")

我使用不同的数据帧在同一图表上添加了不同的轨迹。但是当我将鼠标悬停在每一行时，它只显示 Y 的值。我的问题是当我将鼠标悬停在轨迹上时如何添加更多数据？

P.s 我对每条轨迹使用不同的 csv

Answer 1

以三个股价数据为样本，使用指定y-axis值以外的数据，有自定义数据功能。在这种情况下，指定了一个数据框，并将显示模板格式组合为 html 格式。由于我们将收盘价指定为 y-axis，因此我们使用其他初始价、最高价、最低价和成交量作为悬停数据。

import yfinance as yf
import plotly.graph_objects as go
import pandas as pd

aapl = yf.download("AAPL", start="2021-01-01", end="2022-04-01")
tsla = yf.download("TSLA", start="2021-01-01", end="2022-04-01")
goog = yf.download("GOOG", start="2021-01-01", end="2022-04-01")

fig  = go.Figure()

common_template = ('Open: %{customdata[0]:.2f}<br>' +
'High: %{customdata[1]:.2f}<br>' +
'Low: %{customdata[2]:.2f}<br>' +
'Adj Close: %{customdata[4]:.2f}<br>' +
'Volume: %{customdata[5]}')

    
fig.add_trace(
  go.Scatter(x=aapl.index, y=aapl['Close'],
             name="AAPL", customdata=aapl,
             hovertemplate=common_template
            )

fig.add_trace(
