Question

我想创建一个100％堆积条形图，显示按设备和状态类型分组的状态值持续时间比率。类似于http://demos.telerik.com/kendo-ui/bar-charts/grouped-stacked100-bar。

我设法根据solution制作了部分this answer，但它有一个很大的问题 - 如果我使用系列的堆栈属性，我无法使其成为100％堆叠条。有人知道问题是什么吗？

另一个问题是我想做同样的事情但是使用数据绑定。有可能吗？我不知道如何使用相同的字段数据绑定多个系列？

代码：

您可以通过在每个系列上设置stack.group和stack.type来获得100％的堆栈：

  //convert the data
  dataDS.fetch(function(){
    var view = dataDS.view();

    for (i = 0; i < view.length; i++) {            
      var statusType = view[i];
      for (p = 0; p < statusType.items.length; p++) { 
          var statusValue = statusType.items[p];

          var series = {};
          series.name = statusType.value +":"+ statusValue.value;
          series.stack = {};
          series.stack.group = statusType.value;
          series.stack.type = "100%";
          series.data = [];


          for (j=0; j<statusValue.items.length; j++){
            var data = statusValue.items[j];
            if (i==0 && p==0) {
               thesectors.push(data.device);
            }
            series.field='duration';
            series.data.push(data)

          }
          theseries.push(series);
      }

    }
  });
