为什么python制作图表空白_python – plotly.offline.iplot给出一个大的空白字段作为输出 – 为什么？...

我试图在Jupyter笔记本中创建一个Sankey图表,我的代码基于

the first example shown here.

我最终得到了这个,我可以运行而不会出现任何错误：

import numpy as npy

import pandas as pd

import plotly as ply

ply.offline.init_notebook_mode(connected=True)

df = pd.read_csv('C:\\Users\\a245401\\Desktop\\Test.csv',sep=';')

print(df.head())

print(ply.__version__)

data_trace = dict(

type='sankey',domain = dict(

x = [0,1],y = [0,1]

),orientation = "h",valueformat = ".0f",node = dict(

pad = 10,thickness = 30,line = dict(

color = "black",width = 0.5

),label = df['Node,Label'].dropna(axis=0,how='any'),color = df['Color']

),link = dict(

source = df['Source'].dropna(axis=0,target = df['Target'].dropna(axis=0,value = df['Value'].dropna(axis=0,)

)

print(data_trace)

layout = dict(

title = "Test",height = 772,width = 950,font = dict(

size = 10

),)

print(layout)

fig = dict(data=[data_trace],layout=layout)

ply.offline.iplot(fig,filename='Test')

csv文件看起来像这样：

Source;Target;Value;Color;Node,Label

0;2;2958.5;#262C46;Test 1

0;2;236.7;#262C46;Test 2

0;2;1033.4;#262C46;Test 3

0;2;58.8;#262C46;Test 4

0;2;5.2;#262C46;Test 5

0;2;9.4;#262C46;Test 6

0;2;3.4;#262C46;Test 7

它似乎运行良好,各种输出乍一看,但ply.offline.iplot的最终输出(图,文件名=’测试’)只显示一个大的空白字段：

在运行笔记本中的所有单元格后,终端看起来像这样：

有人可以指点我到哪里错了吗？
