stdrickforce opened a new issue #8284: PieCharts 和 Legend 结合使用时，会产生关键字冲突的问题

   ### One-line summary [问题简述]
   
   pieCharts 在使用 legend 的时候，如果数据和图例的名字都为 get 的话，会报错导致图片无法出来。
   
   稍微看了一下，应该是 createHashmap 占用了 get / set / constructor / each / removeKey 这几个关键字，而 legend 组件用到了 hashmap，从而在业务中包含 get 图例时，get 方法被覆盖，导致错误。
   
   
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]:
   4.1.0
   + Browser version [浏览器类型和版本]:

   + OS Version [操作系统类型和版本]:

       },
       legend: {
           orient: 'vertical',

               type: 'pie',
               radius : '55%',

               data:[
                   {value:335, name:'get'},
                   {value:310, name:'set'},
               ],
