hey @anhltse03448, don' abuse using "@". Someone will help answer questions if possible, but don't do things like this :)

If you want to sync in 2 charts, you should take a look at ChartTransformer and ChartViewPortHandler for some API support. Also, there are people asking such issues several times, you can serach them in old issues.

About zoom, you have to get some knowledge how it works and then you will know how to do it in code.
