</script>原本要求的数据格式是二维数组
series: [{
type: 'area',
name: 'area',
data: [
[1370131200000, 0.7695],
[1370217600000, 0.7648]
]
}]然后get请求的数据返回的时候直接返回二维数组就行了
需要注意的就是二维数组的更新方式
有的时候，当我们手动对data中的数据修改时，vue却监听不到这些数据的变化，导致页面没有触发新一轮的更新。
注意：出现以上问题的原因在于，没有通过vue提供的方法对保存在data中的数据进行修改。强制性通过js对数据修改的那些方法，有一部分在vue中是不被认可的。
对于数组的更新，一种可以使用
另一种则可以通过set方法（）
this.set 这是vue实例调用 set 这是vue实例调用set这是vue实例调用set()方法，专门用来修改数组的
第一个参数，已经存在data中的数据，要被修改的数组
第二个参数，要修改的数组下标
第三个参数，要修改的数组对应下标的值
this.$set (this.selectedarr, index, option)
