xiyang2333 opened a new issue #10977: 散点-pie图中datazoom的问题
URL: https://github.com/apache/incubator-echarts/issues/10977
 
 
   ### What problem does this feature solve?
   在散点-pie的mix图中，pie会在散点图加载后动态替换途中的散点，如果加上datazoom，会导致只有坐标轴被放大而图标不变。
   如果加上监听事件，在zoom后动态再次替换，会导致异常情况发生，请问如何处理这样的问题？
   
   ### What does the proposed API look like?
   function buildPieSeries(){
       // var xAxis = myChart.component.xAxis.getAxis(0);
       // var yAxis = myChart.component.yAxis.getAxis(0);
       var len = sData1.length;
       option.series = option.series.slice(0,3);
       option.legend = {
           data : ['p', 'n', 'e']
       };
       while (len--) {
           var x = myChart.convertToPixel({xAxisIndex: 0}, sData1[len][0]);
           var y = myChart.convertToPixel({yAxisIndex: 0}, sData1[len][1]);
           console.log(x, y);
           option.series.push({
               type: 'pie',
               itemStyle : {
                   normal : {
                       label : {
                           show : false
                       },
                       labelLine : {
                           show : false
                       }
                   }
               },
               radius : sData1[len][2]   sData2[len][2]  sData3[len][2],
               center: [
                   x,y
               ],
               data: [
                   {name: 'p', value: sData1[len][2]},
                   {name: 'n', value: sData2[len][2]},
                   {name: 'e', value: sData3[len][2]}
               ]
           })
       }
       option.animation = true;
       myChart.setOption(option, true);
       window.onresize = buildPieSeries;
   }
   // 构造出一系列的饼图代替原来的散点，需要在散点画出来后才能获取到散点的坐标，setTimeout！
   setTimeout(buildPieSeries, 100);
   
   myChart.on('datazoom', buildPieSeries);
