1.json值

{
    "code": 0,
    "msg": "OK",
    "data": [
        {
            "title": "a",
            "value": "72"

        {
            "title": "h",
            "value": "3"            
        }
    ]
}

Answer 1

var obj = new Array();
var xObj = new Array();
for(var a of data){
xObj.push = a.title;
obj.push = a.value;
}
然后在option里面
x轴的 data:xObj,
数据 data:obj，
