自定義懸停框繪圖：Python 以適應文本

Question

有沒有辦法在 plotly 中自定義懸停文本框？ 我必須在懸停框中顯示的文本很長，無法顯示在屏幕上。 有沒有辦法改變懸停文本框的尺寸或縮小文本以使其適合屏幕。 更好的是圖表側面的固定框，當我滾動該數據點時顯示相應的注釋，但我不知道如何做到這一點。

這是我嘗試對一些相似長度的文本執行的操作的示例。

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')

任何幫助將非常感激！

您可能需要查看注釋以創建固定文本框。 在此處查看我們的文檔： https : //plot.ly/python/text-and-annotations/您將看到如何為注釋或懸停文本指定字體大小。

Answer 2

秘訣是在您的懸停字符串文本中每大約 90 個字符插入一個 html <br> 標簽。 您可以使用下面的正則表達式來匹配每約 90 行。

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