这个示例的Plotly散点图不起作用，您能告诉我为什么吗？

Question

这是代码，来自https://plot.ly/python/line-and-scatter/

import plotly.plotly as py
import plotly.graph_objs as go

# Create random data with numpy
import numpy as np

N = 100
random_x = np.linspace(0, 1, N)
random_y0 = np.random.randn(N)+5
random_y1 = np.random.randn(N)
random_y2 = np.random.randn(N)-5

# Create traces
trace0 = go.Scatter(
    x = random_x,
    y = random_y0,
    mode = 'markers',
    name = 'markers'
)
trace1 = go.Scatter(
    x = random_x,
    y = random_y1,
    mode = 'lines+markers',
    name = 'lines+markers'
)
trace2 = go.Scatter(
    x = random_x,
    y = random_y2,
    mode = 'lines',
    name = 'lines'
)

data = [trace0, trace1, trace2]
py.iplot(data, filename='scatter-mode')

当我将其复制并粘贴到jupyter笔记本中时，出现以下错误：

PlotlyError：因为您没有在调用中提供'file_id'，所以我们假设您正在尝试从URL中获取数字。您提供了网址“”，我们希望它以“ https://plot.ly”开头。 运行此功能的帮助以获取更多信息。

整个错误：

Answer 1

由于代码中的以下微小更改，您应该能够使它工作：

import plotly

plotly.offline.plot(data, filename='basic-scatter')

Answer 2

对于使用pandas的人们来说，另一种解决方案是通过Plotly使用cufflinks交互式熊猫图表。

import cufflinks as cf
cf.go_offline()
