MohammadYounes opened a new issue #11029: Pie expansion animation behavior 
URL: https://github.com/apache/incubator-echarts/issues/11029
 
 
   ### Version
   4.2.1
   
   ### Steps to reproduce
   When loading Pie series along with data, the expansion animation is 
continues,
   
   
![continues](https://user-images.githubusercontent.com/4712046/63129101-55c2cf80-bfbf-11e9-95d5-df17b2058904.gif)
   
   Code Sample:
   ```js
   var data = [
       {"name":"A1B·1","value":92386},
       {"name":"BB1·","value":90611},
       {"name":"1BB","value":12596},
       {"name":"2BA·1","value":9438},
       {"name":"1BA","value":10049}
   ]
       
   option = {
       series : [
           {
               type: 'pie',
               animationType:'expansion',
               animationDuration:5000,
               startAngle:0,
               endAngle:360,
               radius : ['50%','80%'],
               center: ['40%', '50%'],
               data: data // set along with series
           }
       ]
   };
   ```
   
   But when setting the data while the series has already been added, the 
expansion animation becomes discrete (per pie piece).

   Code Sample:
   ```js
   var data = [
       {"name":"A1B·1","value":92386},
       {"name":"BB1·","value":90611},
       {"name":"1BB","value":12596},
       {"name":"2BA·1","value":9438},
       {"name":"1BA","value":10049}
   ]
       
   option = {
       series : [
           {
               type: 'pie',
               animationType:'expansion',
               animationDuration:5000,
               animationDurationUpdate:5000,
               startAngle:0,
               endAngle:360,
               radius : ['50%','80%'],
               center: ['40%', '50%']
           }
       ]
   };
   
   //set after rendering
   setTimeout(function() {
      myChart.setOption({
          series:[
              {
               data: data
              }
           ]
      })
   }, 500);
   ```
   
   Is there away to force continues animation even if data is added later?
   
   ### What is expected?
   Continues Pie Chart Animation
   
   ### What is actually happening?
   Discrete Pie Chart Animation
