多次循环迭代，得到：

var a =[{
    data: [20.0,20.0,20.0,20.0,20.0,...], //随着迭代的次数push
    name: "n相温度",
    type: "line"
},{
    data: [19.7,19.7,19.7,19.7,19.7,...],//随着迭代的次数push
    name: "c相温度",
    type: "line"
},{
    data: [19.9,19.9,19.9,19.9,19.9,...],//随着迭代的次数push
    name: "c相温度",
    type: "line"
},{
    data: [20.1,20.1,20.1,20.1,20.1,...],//随着迭代的次数push
    name: "c相温度",
    type: "line"
}]
