Engine-C commented on issue #10145: bmap下data数据绑定value值失效

   ..自问自答吧。（echart的配置项也太多了） 官方例子那边的tooltip的确有问题。
   
要修改的话，需要自己去定义[tooltip](https://echarts.baidu.com/option.html#series-scatter.tooltip.formatter).
   
   map类的tooltip，看文档是只支持{a}{b}{c} 
c是混合数据，也就是formatter没法用字符串模板去写.官方还提供了了一个回调函数的方法，可以解决这个问题。有点神奇的是这个函数支持返回一个string类型的html模板（并不是jsx），如果有心的话可以玩出花来。
   
   
   ```
   tooltip: {
                   formatter: function (params) {
                         return `<div style='color:#00FFFF'>
                           ${params.data.name}: ${params.data.value[2]}
                         <div>`
                   }
    }
   ```
