如何在Amcharts中迭代json对象

Question

我的代码正在使用Amcharts。我使用ajax post api调用。我已经为数据创建了变量，但我希望它为它创建一个循环。
我正在尝试进行数据操作，但我无法做到。我想创建一个循环，在其中循环迭代json对象并推送到数组，然后将该数组提供给datatprovider来绘制图形
请检查我的代码，然后通知我，或者我可以通过其他任何方式实现。
这是我的代码：

var slot1 = [], Dride = [], Pride = [];
var object = {
  "driver_data": [{
    "slot": 0,
    "rideCount": 98
  }, {
    "slot": 30,
    "rideCount": 75
  }, {
    "slot": 100,
    "rideCount": 0
  }],
  "passenger_data": [{
    "slot": 0,
    "rideCount": 33
  }, {
    "slot": 30,
    "rideCount": 56
  }, {
    "slot": 100,
    "rideCount": 37
  }]
}

object.driver_data.forEach(function(key) {
  slot1.push(key.slot);
  Pride.push(key.rideCount)
});

object.passenger_data.forEach(function(key) {
  slot1.push(key.slot);
  Dride.push(key.rideCount);
});

var myObj = {}, myObj1 = {}, myObj2 = {}, arr = [];

myObj["slot"] = slot1[0];
myObj["passenger_data"] = Pride[0];
myObj["driver_data"] = Dride[0];

myObj1["slot"] = slot1[1];
myObj1["passenger_data"] = Pride[1];
myObj1["driver_data"] = Dride[1];

myObj2["slot"] = slot1[2];
myObj2["passenger_data"] = Pride[2];
myObj2["driver_data"] = Dride[2];

arr.push(myObj, myObj1, myObj2)
console.log(JSON.stringify(arr))
