echarts大数据量问题

5

### Version 4.9.0 ### Steps to reproduce 目前业务层面上的数据可能会在几十万上下,但是使用echarts去渲染时特别卡顿,无论是dataset模式还是常规模式都一样,使用svg方式渲染也是一样! 一般模式 https://www.makeapie.com/editor.html?c=xxAa4x9w_Y dataset模式 https://www.makeapie.com/editor.html?c=xJm15mIBjf&v=1 ### What is expected? 可有对大数据量(几百万甚至上千万)渲染的解决方案? 1 . 比如虚拟渲染啥的,一开始数据点全部挤在一块,就按照平均取值对X轴和数据进行部分渲染,鼠标滚轮滚动在逐一渲染 2. 如地图形式一样,拖拽缩放地图,就渲染当前可视区的数据 ### What is actually happening? 大数据量情况下,echarts渲染操作特别卡
