【问题描述】：

有没有办法在 plotly 中自定义悬停文本框？我必须在悬停框中显示的文本很长，不适合屏幕。有没有办法改变悬停文本框的尺寸或缩小文本以使其全部适合屏幕。 更好的是图表侧面的固定框，当我滚动该数据点时显示相应的注释，但我不知道该怎么做。

这是我尝试使用一些类似长度的文本的示例。

import plotly.plotly as py
from plotly.graph_objs import *
import plotly
import matplotlib.pyplot as plt
import numpy as np
import pandas as pd

balance=[1000,2000,4000]
dates=[1,2,3]


data1 = Data([
    Scatter(
        x=dates,
        y=balance,
        mode='markers',
        text=notes,        
    )
])
layout = Layout(
    title='Hover over the points to see the text',autosize=True,   
)
fig = Figure(data=data1, layout=layout,)

fig['layout'].update(
    hovermode='closest',  
    showlegend=False,     
    autosize=True,       

)
plot_url = py.plot(fig, filename='hover-chart-basic')
py.plot(fig, filename='hover-chart-basic')

任何帮助将不胜感激！

【参考方案1】：

您可能需要查看注释以创建固定文本框。在此处查看我们的文档：https://plot.ly/python/text-and-annotations/ 您将了解如何为注释或悬停文本指定字体大小。

【参考方案2】：

秘诀是在悬停字符串文本中每隔约 90 个字符插入一个 html 标签。您可以使用下面的正则表达式来匹配每 ~90 行。
