Plotly-Dash显示错误的图形(线形图而不是漏斗图)

Question

我正在尝试使用dash和plotly显示一个简单的漏斗图。问题是它显示的是折线图。

我遵循了this answer中的说明，即使用以下代码：

app = dash.Dash()

app.layout = html.Div([dcc.Graph(id='FunnelDashboard',
                figure = {'data':[
                        go.Funnel(
                        y = ["Website visit", "Downloads", "Potential customers", "Requested price", "invoice sent"],
                        x = [39, 27.4, 26.6, 11, 2])]
                        }
                        )])
if __name__ == '__main__':
    app.run_server()

但是我得到的是this线条图。

我期望得到的是类似于this的东西。

Answer 1

更新破折号：

pip install -U dash

在1.9.1版本中，使用以下代码：

import dash
import dash_html_components as html
import dash_core_components as dcc
from plotly import graph_objects as go

fig = go.Figure(go.Funnel(
    y = ["Website visit", "Downloads", "Potential customers", "Requested price", "invoice sent"],
    x = [39, 27.4, 20.6, 11, 2]))


external_stylesheets = ['https://codepen.io/chriddyp/pen/bWLwgP.css']

app = dash.Dash(__name__, external_stylesheets=external_stylesheets)


app.layout = html.Div([dcc.Graph(id='FunnelDashboard',
                    figure=fig)])

if __name__ == '__main__':
    app.run_server()

你会得到：
