URL: https://github.com/apache/incubator-echarts/issues/8891
 
 
   <!--
   为了方便我们能够复现和修复 bug，请遵从下面的规范描述您的问题。
   -->
   
   
   ### One-line summary [问题简述]
   一个线性图表, 初始数据[1, 2, 3]会正常的出现动画效果, 2秒后异步追加数据[4, 5, 6], 会是直接出现的, 而不是动画
   
   
   
   
   ### Version & Environment [版本及环境]
   + ECharts version [ECharts 版本]:4.1.0.rc2
   + Browser version [浏览器类型和版本]:chrome 68.0.3440.84  64bit
   + OS Version [操作系统类型和版本]:macos 64bit
   
   
   
   
   
   ### Expected behaviour [期望结果]
   和初始数据一样使用动画效果过度加载
   
   
   
   
   ### ECharts option [ECharts配置项]
   <!-- Copy and paste your 'echarts option' here. -->
   <!-- [下方贴你的option，注意不要删掉下方 ```javascript 和 尾部的 ``` 字样。最好是我们能够直接运行的 option。如何得到能运行的 option 参见上方的 guidelines for contributing] -->
   ```javascript
   data = [1, 2, 3]
   option = {
       xAxis: {
         type: 'category',
         data: ['Mon', 'Tue', 'Wed', 'Thu', 'Fri', 'Sat']
       },
       yAxis: {
         type: 'value'
       },
       series: [{
         data: data,
         type: 'line',
         smooth: true
       }]
   }
   
   // 这里是追加数据时的代码 (也使用appendData尝试过, 效果一样)
   setTimeout(function () {
      data.push.apply(data, [4, 5, 6])
      chart.setOption(option)
   }, 2000)
   ```
