Plotly.js 创建堆叠和分组条形图

Question

如何在Plotly.js上创建带有分组和堆叠条形的条形图？我需要这样的结构： 带有堆叠和分组图表的条形图

Answer 1

通过将每个组创建为子图，可以在 Plotly.js 中创建分组堆叠条形图。它并不像设置“barmode”这样的顶级功能那么简单：“stacked+grouped”，但因为它更基本，所以提供了更多选项。

请参阅https://community.plot.ly/t/combination-of-grouped-and-stacked-bar-chart/2154

这里每个子图引用一个共享的公共 y 轴和它自己的 x 轴。每个 x 轴都有一个“域”，这里表示整个底部轴宽度的一部分。这里第一组得到 [0.0, 0.33]，第二组得到 [0.34, 0.66]，第三组得到 [0.67, 1.0]

   Plotly.newPlot(
  "myDiv",
