Python Anaconda 3.6 plotly模块使用图

Question

似乎无法正常工作：

import plotly.offline as pyo
from plotly.graph_objs import *
import plotly.plotly as py
import pandas as pd
from pandas import DataFrame

pyo.offline.init_notebook_mode() 


trace1 = {'type' : 'scatter',
          'x' : [1,2,3,4,5,6,7,8,9],
          'y' : [1,2,3,4,5,6,7,8,9],
          'name' : 'trace1',
          'mode' : 'lines'}

layout = {'title' : 'my first plotly chart',
          'xaxis' : {'X Values'},
          'yaxis' : {'Y Values'}        
          }

data = Data([trace1])

fig = Figure(data = data, layout = layout)

python 指出数据已折旧，并要求我使用其他东西，但我似乎无法弄清楚。

看起来您在创建 figure 后错过了绘图命令。 Data([trace1]) 错误地寻找我的意见。因此，如果您想使用 Python3 创建一个简单的散点图，您可以通过两种方式进行（并给出相同的结果）。
1.First方式：

# Import all the necessaries libraries
import plotly.offline as py
import plotly.graph_objs as go
import pandas as pd
# In trace you specify what kind of plot you want (such scatter, bar, pie or so)
trace = go.Scatter(
      x=[1,2,3,4,5,6,7,8,9],
      y=[1,2,3,4,5,6,7,8,9],
      name="trace1",
      mode="lines")
# Data is just the list of your traces
data = [trace]
# Create layout if you want to add title to plot, to axis, choose position etc
layout = go.Layout(
      title="My first plotly chart",
      xaxis=dict(title="X Values"),
      yaxis=dict(title="Y Values"))
# Figure need to gather data and layout together
fig = go.Figure(data=data, layout=layout)
# This commandd plot the plot and create HTML file in your Python script directory
py.iplot(fig, filename="first plot.html")

2.Second方式：

# Import all the necessaries libraries
import plotly.offline as py
import plotly.graph_objs as go
import pandas as pd
# This code have the same result as previous, but it is more unreadable as I think
fig = {
  "data": [
    {
      "x": [1,2,3,4],
      "y": [1,2,3,4],
      "name": "trace1",
      "type": "scatter"
    }],
  "layout": {
        "title":"My first plotly chart",
        "xaxis": {
                "title": "X Values"
                },
        "yaxis": {
               "title": "Y Values"
               }
            }
    }
# Just plot
py.iplot(fig, filename="first plot.html")

如果你想自定义你的情节，我建议你检查plotly docs about scatter plot。
