[GitBox]

Erin-mm opened a new issue #15071:
URL: https://github.com/apache/echarts/issues/15071


   ### Version
   5.1.1
   
   ### Steps to reproduce
   项目涉及到江西省南昌市的地图数据，要求使用tooptip轮播南昌市下每个县级单位的数据。所以用定时器如下代码来控制
   ```
    this.echartRef.getEchartsInstance().dispatchAction({
         type: 'showTip', //控制提示框出现
         seriesIndex: 0,
         dataIndex: count,
       });
   ```
   南昌市地图如下所示：

   其中青山湖区在新建区的中心，东湖区在青山湖区中心，所以tooptip在轮播到青山湖区的时候会显示成东湖区的数据，到新建区则会显示青山湖区的数据
   
   ### What is expected?
   能正确显示tooptip信息
   
   ### What is actually happening?
   tooptip信息读取错误
