Help with easy chart

Hi, I have a Main Windows with two buttons and a popup window with a Easy chart, I want to show a group of tags when I press the first button and show other group of tags when I press the second button, How can I do that? How can I tell to the easy chart what tag to show? I have two identical UDT I want to send a parameter but I can’t do it, can you send me some example? thanks.

thanks but already solved, :slight_smile: I saw the youtube videos, there is a example to do this.
