【问题描述】:
我正在尝试这段简单的代码,它正在引发标题中提到的异常。
import dash
import dash_core_components as dcc
import dash_html_components as html
import plotly.graph_objs as go
import pandas as pd
df=pd.read_excel("https://github.com/chris1610/pbpython/
blob/master/data/salesfunnel.xlsx?raw=True")
pv = pd.pivot_table(df, index=['Name'], columns=["Status"], values=
['Quantity'], aggfunc=sum, fill_value=0)
trace1 = go.Bar(x=pv.index, y=pv[('Quantity', 'declined')], name='Declined')
trace2 = go.Bar(x=pv.index, y=pv[('Quantity', 'pending')], name='Pending')
trace3 = go.Bar(x=pv.index, y=pv[('Quantity', 'presented')], name='Presented')
trace4 = go.Bar(x=pv.index, y=pv[('Quantity', 'won')], name='Won')
app = dash.Dash()
app.layout = html.Div(children=[
html.H1(children='Sales Funnel Report'),
html.Div(children='''National Sales Funnel Report.'''),
dcc.Graph(
id='example-graph',
figure={
'data': [trace1, trace2, trace3, trace4],
'layout':
go.Layout(title='Order Status by Customer', barmode='stack')
})
])
所以,它指向程序的最后一行,即 go.Layout 并提到了这个错误。 我已经尝试了很多东西,但我找不到这个错误的原因。如果有人能解决这个问题,那将是很大的帮助。 提前致谢, 问候
