plotly中的漏斗图

Question

我正试着用plotly创建一个漏斗图，但没有任何运气。即使是plotly中的固定例子对我也不起作用，有人能帮我吗？

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]))

fig.show()

我得到了这个巨大的回溯错误：

lueError:接收到的'data‘属性的'plotly.graph_objs.Funnel’类型的值无效:漏斗({ 'x'：39，27.4，20.6，11，2，'y'：网站访问，下载，潜在客户，请求价格，已发送发票})

The 'data' property is a tuple of trace instances
that may be specified as:
  - A list or tuple of trace instances
    (e.g. [Scatter(...), Bar(...)])
  - A list or tuple of dicts of string/value properties where:
    - The 'type' property specifies the trace type
        One of: ['area', 'bar', 'barpolar', 'box',
                 'candlestick', 'carpet', 'choropleth', 'cone',
                 'contour', 'contourcarpet', 'funnel',
                 'funnelarea', 'heatmap', 'heatmapgl',
                 'histogram', 'histogram2d',
                 'histogram2dcontour', 'isosurface', 'mesh3d',
                 'ohlc', 'parcats', 'parcoords', 'pie',
                 'pointcloud', 'sankey', 'scatter',
                 'scatter3d', 'scattercarpet', 'scattergeo',
                 'scattergl', 'scattermapbox', 'scatterpolar',
                 'scatterpolargl', 'scatterternary', 'splom',
                 'streamtube', 'sunburst', 'surface', 'table',
                 'violin', 'volume', 'waterfall']

    - All remaining properties are passed to the constructor of
      the specified trace type

    (e.g. [{'type': 'scatter', ...}, {'type': 'bar, ...}])

看起来您正在使用版本3，在这种情况下，您将需要使用go.Figure(data=[go.Funnel(...)]) (基本上将漏斗跟踪包装在一个数组中……只有在版本4中才是可选的)
