Javascript 将对象转换为typescript中的列表列表

我正在从Angular 5进行API调用，响应格式如下

{   "metadata":{
      "lastSyncTime":"2000-11-21T16:07:53",
      "dataFromDB":true
   },
   "allocationReports":[      {
         "allocatedUserCount":100,
         "healthGoalName":"Eat Healthier"
      },
      {
         "allocatedUserCount":130,
         "healthGoalName":"Feel Happier"
      },
  
      {
         "allocatedUserCount":150,
         "healthGoalName":"Quit Smoking"
      }
   ],
   "overall":{
      "usersWithGoalCount":0,
      "registeredCount":500,
      "eligibleCount":280
   }
}

我需要将这些数据转换为列表列表（或数组数组），以便在此数据上绘制多个圆环图。我尝试了多种方法，比如使用.map，但是在单个列表中获取所有值。如何以以下格式构建数据

{   "metadata":{
      "lastSyncTime":"2000-11-21T16:07:53",
      "dataFromDB":true
   },
   "allocationReports":[      {
         "allocatedUserCount":100,
         "healthGoalName":"Eat Healthier"
      },
      {
         "allocatedUserCount":130,
         "healthGoalName":"Feel Happier"
      },
  
      {
         "allocatedUserCount":150,
         "healthGoalName":"Quit Smoking"
      }
   ],
   "overall":{
      "usersWithGoalCount":0,
      "registeredCount":500,
      "eligibleCount":280
   }
}

所需格式为：

[ 
 [
  { "x": "Eat Healthier", "y": 100 },
  { "x": "Total registered", "y": 500 } 
 ],
 [
  { "x": "Feel Happier", "y": 130 },
  { "x": "Total registered", "y": 500 } 
 ],
 [
  { "x": "Quit Smoking", "y": 150 },
  { "x": "Total registered", "y": 500 } 
 ]
]

总的注册值将来自

总体。registeredCount

试试这个

ob={“metadata”：{“lastSyncTime”：“2000-11-21T16:07:53”，“dataFromDB”：true}，“分配报告”：[{“allocatedUserCount”：100，“healthGoalName”：“吃得更健康”}，{“allocatedUserCount”：130，“healthGoalName”：“感觉更快乐”}，{“allocatedUserCount”：150，“healthGoalName”：“戒烟”}]，“总体”：{“usersWithGoalCount”：0，“registeredCount”：500，“eligibleCount”：280}
r=ob.allocationReports.map（o=>{return[{x:o.healthGoalName，y:o.allocatedUserCount}，{x:“已注册总数”，y:ob.Total.registeredCount}]）
console.log（r）

如果您能提供帮助，请再问一个问题。我们可以按“allocatedUserCount”的升序对结果数组进行排序吗。
