ahmadalibaloch opened a new issue #9232: Use OffScreenCanvas API for big data live charts URL: https://github.com/apache/incubator-echarts/issues/9232 <!-- 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] I am creating an application which shows years of historic data and also keeps plotting new live data from a web socket connection, I am facing real performance issues and UI thread goes blocking, I have been searching on it and I think the solution is this. **Make use of** [OffScreenCanvas API](https://developers.google.com/web/updates/2018/08/offscreen-canvas) to render live charts with big data smoothly. It is really easy to use with just one line amendment. `canvasElement.transferControlToOffscreen()` ### Expected behaviour [期望结果] Live charts with big data should work smoothly.
