Plotly-Dash 顯示錯誤的圖形（線圖而不是漏斗圖）

Question

我正在嘗試使用破折號和繪圖顯示一個簡單的漏斗圖。 問題是它顯示了一個折線圖。

我按照this answer中的說明進行操作，即使用了代碼：

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()

但我得到了這條線圖。

我期望得到的是這樣的。

Answer 1

更新破折號：

pip install -U dash

使用版本1.9.1 ，使用以下代碼：

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()

你得到：
