javascript - highchart 旭日百分比，不是相对百分比，而是取决于其他属性

Question

我用 Angular 制作了一个森伯斯特 Highcharts 。对于第一级，我直接计算所有其他级别的总和，对于第三级，我使用了 point.value ，它也是 passAssetCnt/totalAssetCnt * 100 但对于第二级，这样就不行了。

这是我的格式化函数。我的目标是计算百分比，如果它们具有相同的 reqnum，则为 passAssetCnt/totalAssetCnt * 100。

一切都很好，直到我做出将绘制百分比的返回声明而且一切都归零。

我尝试在格式化程序函数中调用一个单独的函数，该函数将完成所有这些操作，但也没有被调用。

Answer 1

终于能够通过重新创建数组然后再次与每个点进行比较来解决这个问题。

 var res =   this.point.series.userOptions.data.reduce((acc, obj)=>{
  var existItem = acc.find(item => item.reqnum === obj.reqnum);
  if(existItem){
    existItem.passAssetCnt += obj.passAssetCnt;
     existItem.totalAssetCnt += obj.totalAssetCnt;
    return acc;
  } 
  acc.push(obj);
  return acc;
}, []);



var j;
for (j = 0; j < res.length; j++) { 
    if(res[j].name == this.point.name) {
        console.log(this.point.name + '<br>' + Math.round(res[j].passAssetCnt/res[j].totalAssetCnt*100) + '%');     
 return this.point.name + '<br>' + Math.round(res[j].passAssetCnt/res[j].totalAssetCnt*100) + '%';
 }
}
