如何将所有这些数组值推入单个数组？

Question

我需要在深入的图表中传递值，我的JSON格式无法正常工作，所以请帮我解决这个问题。

public function actionIndex ()
        {
            $array = [];  // for array result 
            $field1 =  '';  // if fix value $field1 =  'a'; can pass a to $result
            $field2 =  '';  // if fix value $field2 =  'b'; can pass b to  $result

                 if (Yii::$app->request->isPost)  
             {
                $FISTL =  $_POST['field1'];  // view ~field1
                $FIPEX =  $_POST['field2'];  // view ~field2
             }

        if($field1 !== '' && $field1 !== ''){    *// add if condition for get variable*
            $connection = Yii::$app->sconnection->connectionToAnotherSystem(); // connection to another system
            $result = $connection->getValue([     
                'field1' => $field1,    // if fix value $field1 =  'a'; can pass a to $result
                'field2' => $field2,    // if fix value $field2 =  'b'; can pass b to  $result
            ]);
            $array = array(['value' =>$result]);//return value from another system 

            } $dataProvider = new ArrayDataProvider([
                'allModels' => $array,
            ]);
            return $this->render('index',
                [
                'dataProvider' => $dataProvider, // true data
                ]);
        }

我的JSON格式如下，

this.MemberProvider.totalMonthlyRevenueByBranch(getmonthmonthwisr)
.subscribe(data => {

 this.graphdata =data;
 console.log(this.graphdata);

})

如何获取这种JSON结构

[
   {
      "_id":{
         "year":2018
      },
      "data":[
         {
            "year":2018,
            "total":10260,
            "month":"Mar"
         }
      ],
      "overall":10260
   },
   {
      "_id":{
         "year":2019
      },
      "data":[
         {
            "year":2019,
            "total":14160,
            "month":"Dec"
         },
         {
            "year":2019,
            "total":14160,
            "month":"Nov"
         },
         {

            "total":14259,
            "month":"Oct"
         },
         {
            "year":2019,
            "total":14160,
            "month":"Sep"
         },
         {
            "year":2019,
            "total":14259,
            "month":"Aug"
         },
         {
            "year":2019,
            "total":14160,
            "month":"July"
         },
         {
            "year":2019,
            "total":28518,
            "month":"Jun"
         },
         {
            "year":2019,
            "total":14259,
            "month":"May"
         },
         {
            "year":2019,
            "total":185185,
            "month":"Apr"
         },
         {
            "year":2019,
            "total":54739,
            "month":"Mar"
         },
         {
            "year":2019,
            "total":28518,
            "month":"Feb"
         },
         {
            "year":2019,
            "total":28518,
            "month":"Jan"
         }
      ],
      "overall":424895
   }
]

这是我很快想到的。优化此代码由您决定。您可能使用for-loop而不是map。完全由您决定

var data = [
   {
      "_id":{
         "year":2018
      },
      "data":[
         {
            "year":2018,
            "total":10260,
            "month":"Mar"
         }
      ],
      "overall":10260
   },
   {
      "_id":{
         "year":2019
      },
      "data":[
         {
            "year":2019,
            "total":14160,
            "month":"Dec"
         },
         {
            "year":2019,
            "total":14160,
            "month":"Nov"
         },
         {
            "year":2019,
            "total":14259,
            "month":"Oct"
         },
         {
            "year":2019,
            "total":14160,
            "month":"Sep"
         },
         {
            "year":2019,
            "total":14259,
            "month":"Aug"
         },
         {
            "year":2019,
            "total":14160,
            "month":"July"
         },
         {
            "year":2019,
            "total":28518,
            "month":"Jun"
         },
         {
            "year":2019,
            "total":14259,
            "month":"May"
         },
         {
            "year":2019,
            "total":185185,
            "month":"Apr"
         },
         {
            "year":2019,
            "total":54739,
            "month":"Mar"
         },
         {
            "year":2019,
            "total":28518,
            "month":"Feb"
         },
         {
            "year":2019,
            "total":28518,
            "month":"Jan"
         }
      ],
      "overall":424895
   }
];
var res = [];
data.map((item, index) =>  {
  const overall = item.overall;
  item.data.map(i => {
  	res[index] = Object.assign(res[index] || {}, {[i.month]: i.total});
  });
  res[index] = Object.assign(res[index], {
  overall, year: item._id.year
  });
  return res;
});

document.body.innerHTML = '<pre>' + JSON.stringify(res, null, '  ') + '</pre>';
