绘图-如何突出显示同一绘图中两个图形的两个结果

Question

我在Python版本3中使用了plotly，并且有一个图，其中有两行是不同的图形，例如。我想同时用鼠标突出显示上下图中的两个值！我的代码如下：

trace0 = go.Scatter(
    x=df.date,
    y=df.price,
    name='Volume',
    line=dict(
        color='rgb(205, 12, 24)',
        width=4)
)

trace1 = go.Scatter(
    x=df.date,
    y=df.sentiment,
    name='Sentiment',
    mode='lines+markers',
    line=dict(
        color='rgb(22, 96, 167)',
        width=4)
)

fig = tools.make_subplots(rows=2, cols=1)

fig.append_trace(trace0, 1, 1)
fig.append_trace(trace1, 2, 1)

fig['layout'].update(height=600, width=800, title='Sentiment Analysis on Social Media')
py.plot(fig, filename='simple-subplot-with-annotations')

Answer 1

用以下内容替换“ fig = tools.make_subplots（rows = 2，cols = 1）”

import plotly.offline as py
import plotly.graph_objs as go    
data = [trace0, trace1]  
layout = go.Layout(
    title = 'Sentiment Analysis on Social Media')
fig = go.Figure(data=data,layout=layout)
py.plot(fig, filename='simple-subplot-with-annotations.html')
