rollYouth commented on issue #12399: 关于canvas中折线超过12000不显示 URL: https://github.com/apache/incubator-echarts/issues/12399#issuecomment-610871835 > 这个宽度，Canvas 的绘制跟浏览器和硬件会有很大的关系了（我刚在高分屏上用 35000 的分辨率显示就崩溃了，因为要分配的内存太大了） > > 你的数据量大概是多少？如果可以的话可以试试开启 sampling，我刚试了 100w 的数据，开启 sampling 后交互也是挺流畅的 现在我们考虑用多个canvas组合起来使用，测试用了40个canvas目前没有问题，不知道会不会有其他的坑 <img width="1409" alt="history2" src="https://user-images.githubusercontent.com/56584514/78772274-16207c00-79c4-11ea-9ab9-99b5532bfcd2.PNG";>
