Adele0 opened a new issue #10406: 异步多条line图形页面渲染出错
URL: https://github.com/apache/incubator-echarts/issues/10406
 
 
   ### Version
   4.2.1
   
   ### Steps to reproduce
   ```
   this.chart.setOption({
               legend: {
                 data: (function (){
                   let list = [];
                   for (let i = 0; i < _this.chartData.length; i  ) {
                     list.push(_this.chartData[i].shipperName);
                   }
                   return list;
                 })()
               },
               series: 
                 (function () {
                   let list = [];
                   for (let i = 0; i < _this.chartData.length; i  ) {
                     let obj = {
                       name:  _this.chartData[i].shipperName,
                       type: 'line',
                       stack: '总量',
                       data: (function (){
                         let inner = []
                         _this.chartData[i].statistics.map((item) => {
                           inner.push(item)
                         })
                         return inner;
                       })()
                     }
                     list.push(obj)
                     debugger
                   }
                   return list;
                 })(),
             })
   ```
   
   ### What is expected?
   异步多次添加折线，多条折线的数据在视图上正常显示
   
   ### What is actually happening?
   多条折线显示数据不能同时正确显示，其他折线隐藏的情况下，数据正常

   ## 补充
   
   // 不知道怎么在本issue中添加图片（希望我的文字描述能达到图片的效果）
   
   业务场景：用户每次点击按钮（回车）请求一次后台，得到一条折线
   
   发现bug的场景：添加第一条折线，调试工具里看到的series里的data为[0,0,0,0,2]，折线数据也没有问题；添加第二条折线，调试工具里看到的series里的data为[0,0,0,0,2]和[0,0,0,0,0]，视图显示却是第二条折线与第一条折线重合。分别点击隐藏折线时，数据和折线能对应上，但是同时显示还是出现两条折线重叠的情况。
