与chart.js的垂直的被堆积的长条图

Question

来自chart.js的优秀免费图书馆。我将我的图表从Google图表转移到chart.js，因为我可以离线使用它们，它似乎对窗口大小的变化更敏感。此外，我意识到我在中国的观众无法看到我的谷歌图表，因为谷歌的服务在中国被封锁了。

我一直在阅读有关stacked vertical bar charts的文档，但我无法弄清楚如何制作这样的图表。在我看到的堆叠条形图的所有示例中，每个条的项数相同。

我只能制作两个垂直堆叠的数据集吗？这是因为右边的条比左边的条有更多。或者，我需要n数据集，n项目数，是否包含更多项目？

代码

我想为每个（堆叠）条组合一个数据集，但我不能。

var labels = ["standing costs", "running costs"];
var dataset = [

垂直堆积条形图

var chart = new Chart(ctx, {
   type: 'bar',
   data: {
      labels: ['Standing costs', 'Running costs'], // responsible for how many bars are gonna show on the chart
      // create 12 datasets, since we have 12 items
      // data[0] = labels[0] (data for first bar - 'Standing costs') | data[1] = labels[1] (data for second bar - 'Running costs')
      // put 0, if there is no data for the particular bar
      datasets: [{
         label: 'Washing and cleaning',
         data: [0, 8],
         backgroundColor: '#22aa99'
