我有一个散点图,每个点都有悬停文本。如果我在圆圈中绘制,悬停功能将起作用,否则悬停功能将不起作用。(例如,如果我以正方形绘制,则悬停文本不会显示)

从浏览器收到错误消息:Uncaught TypeError: Cannot read property .. at Object.hoverPoints

真的不知道,你在这里做错了什么,但它按预期对我有用:

在此处输入图像描述

代码:

import plotly.plotly as py
import plotly.graph_objs as go
import plotly.offline as pyo

# Create random data with numpy
import numpy as np

N = 1000
random_x = np.random.randn(N)
random_y = np.random.randn(N)

# Create a trace
trace = go.Scatter(
    x = random_x,
    y = random_y,
    mode = 'markers',
    marker = ({'symbol':'triangle-left'})

)

data = [trace]

pyo.plot(data)

参考标记样式
