自定义悬停框图：Python 来适应文本

Question

有没有办法在绘图中自定义悬停文本框？我必须在悬停框中显示的文本相当长，不适合屏幕。有没有办法更改悬停文本框的尺寸或缩小文本以使其全部适合屏幕。 更好的是图表一侧有一个固定框，当我滚动该数据点时显示相应的注释，但我不知道如何做到这一点。

这是我尝试对一些相似长度的文本执行操作的示例。

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！

您可能需要查看注释来创建固定文本框。请在此处查看我们的文档：https://plot.ly/python/text-and-annotations/ 您将了解如何指定注释或悬停文本的字体大小。

秘密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。

(.{1,90})(\\s|$)
