   You can reproduce this on any browser. 
   Example: 
   - https://ecomfe.github.io/echarts-examples/public/editor.html?c=dynamic-data2
   - change setInterval function to this:
   ```
   setInterval(function () {
   
       for (var i = 0; i < 50; i++) {
           data.push(randomData());
       }
   
       myChart.setOption({
           series: [{
               data: data
           }]
       });
   }, 200);
   ```
   
   This will happen with any chart component, because for each pixel on the screen, the average value of the points below has to be calculated - for about 1200 px every 200ms (see above).
   
   @Ajaxluo  - What do you want to display with your chart exactly, can you please attach the rest of the Option structure? Do you need to display all values, or just a partial view?
   您希望在图表中准确显示什么，是否可以附加选项结构的其余部分？您需要显示所有值，还是只显示部分视图？
