   ### One-line summary [问题简述]
   官方文档给出的 如下:
   series[i]-line.label.formatter
   {
       componentType: 'series',
       // 系列类型
       seriesType: string,
       // 系列在传入的 option.series 中的 index
       seriesIndex: number,
       // 系列名称
       seriesName: string,
       // 数据名,类目名
       name: string,
       // 数据在传入的 data 数组中的 index
       dataIndex: number,
       // 传入的原始数据项
       data: Object,     **!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!该参数存在bug**
       // 传入的数据值
       value: number|Array,
       // 数据图形的颜色
       color: string,
   
   }
   
   而实际获取的数据如下
   {
   ...
   data: 1,   **//这里取到的不是一个object ,**
   dataValue: 1,   //这个和data取的值一样
   }

   + Browser version [浏览器类型和版本]: chrome 61+
   + OS Version [操作系统类型和版本]: window 10+
   
   
   
   
   
   ### Expected behaviour [期望结果]
