   @AricZhu 我们在 echarts 5.0 中对折线图性能做了重点的优化，如果使用静态的 Float64Array 作为数据源，可以做到 1s 内渲染完一千万的数据，已经不需要增量渲染了。例子链接 https://jsfiddle.net/ob81ap3q/ 。
   
   另外一些这次优化相关的链接 https://github.com/apache/incubator-echarts/pull/13314 https://github.com/apache/incubator-echarts/pull/13337
   
   另外新增加的 LTTB 采样应该能解决你说的“损害了原始数据的展示”的问题
