//例如，後臺返回的資料為：

var json = {

data: [



{value:103.95,name:"法拉利"},

{value:103.2,name:"北汽幻速"},

{value:97.44,name:"WEY"},

{value:89.46,name:"北汽紳寶"},

{value:88.87,name:"比速汽車"},

{value:88.05,name:"漢騰汽車"},

{value:85.96,name:"五十鈴"}

]

};

//但是前臺需要的資料格式為：

var newData = [

{name:"法拉利",data: [103.95],type:"bar"},

{name:
 
"北汽幻速",data: [103.2],type:"bar"},

{name:"WEY",data: [97.44],type:"bar"},

{name:"北汽紳寶",data: [89.46],type:"bar"},

{name:"比速汽車",data: [88.87],type:"bar"},

{name:"漢騰汽車",data: [88.05],type:"bar"},

{name:"五十鈴",data: [85.96],type:"bar"}

];

//實現的方法為：

//第一步：宣告三個空陣列，分別儲存 value、nam、儲存新物件的值;

var val = [];

var nam
 
= [];

var newData = [];

for(var i = 0; i < json.data.length; i++){

val.push(json.data[i].value);

nam.push(json.data[i].name);

var obj = {

name: json.data[i].name,

data: [json.data[i].value],

type: 'bar'

};

newData.push(obj);

}

console.log('newData', newData);

//目前這個newData就是所需要的新資料。
