Ka-Houl commented on issue #10750: echarts3.*后的版本，雷达图不支持展示单个维度的数据
URL: https://github.com/apache/incubator-echarts/issues/10750#issuecomment-506647003
 
 
   @Ovilia  在formatter回调函数参数params中，未能找到相应端点坐标index，因而似乎判断不出鼠标是移动到了雷达图的哪个端点位置上
   formatter: (params: Object|Array, ticket: string, callback: (ticket: string, html: string)) => string
   
   文档中params的介绍如下
   {
       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,
       // 传入的数据值
       value: number|Array,
       // 数据图形的颜色
       color: string,
   
       // 饼图的百分比
       percent: number,
   
   }
