I want this easy chart's tag path could be dynamic. But I only can choose a certain tag. Is that possible I can use the function like indirect tag or expression to make tag path dynamic?

EasyChart is a _Vision_ component. It cannot be used in _Perspective_. (You have tagged your question as _Perspective_.)

No, you cannot simply embed a dynamic element with curly braces.

There are two possibilities:

- If only changing the path or limited properties of otherwise pre-configured pens, you can use [Cell Update Bindings](https://docs.inductiveautomation.com/display/DOC81/Cell+Update+Bindings) to substitute into the `pens` or `tagPens` configuration dataset properties.

- If the number of pens is also dynamic, you can construct those configuration datasets with scripts, typically using [system.dataset.toDataSet()](https://docs.inductiveautomation.com/display/DOC81/system.dataset.toDataSet). You need to match the column names and types those config properties expect.
