Could someone help me changing a PowerChart's props that is in another view? Context: Screen 1 -\> Has 10 buttons and each one represents a tag. Those 10 buttons open the same pop up (screen 2) Screen 2 -\> Just has a PowerChart inside it, and I need to show on graph only those that I've clicked on. Ex: Click button 1 (PowerChart's content (tag1)), Click button 3 (PowerChart's (tag1 and tag3)) and then sucessively I've already tried to use message to run a script to append the axis and pen that I need, but when I close the PopUp it seems to deletes the previous axis and pen that I appended, idk. ---

You don't want to do this (specifically code screen 1 to know about the contents of screen 2). It's an antipattern that's inherently fragile (what if you decide to add another container to screen 2, or change the name of a component, or whatever?). Send a message from screen 1 that just indicates which tag was selected. Have a message handler on screen 2 that listens for the "a tag was selected" message. In that message handler, (or, by invoking a custom script on your chart) do your axis manipulation. That way you've "separated concerns" - the list of buttons is only in charge of dictating which tag was selected. The chart is in charge of reacting to a tag being selected. ---

I was doing the following sequence: - Button -\> Open pop up -\> Send the message with a payload that contais just the tag that I want to add; - In the PowerChart's screen, I'm using the root the message handler. - The root uses that tag on a script to it add correctly on the graph. But, it just add after I click again on the button behind the pop up. On the first click it just open the pop-up with no information on the graph. ps: If I add it using the double click that I mentioned before, close the pop-up and open again with a normal button, all the changes that the double click made is deleted. Hope it was clear 😰 ---

That's because you're sending a message before the handler is listening. For the first tag, pass it as a parameter to the popup and add it from there. You can send a message from the on change script of parameters, but a simple binding should be enough - the powerchart data shouldn't be reset if the parameter doesn't change, which should not happen. You may want to wait for confirmation on that. ---

I started to use this on change script as you suggested, it's working. But I don't want to reset the powerchart data, is there a way to do it? ---

After searching about it I got the idea to create it on session custom prop and link it Then the popup don't reset its data when I close it. Thanks you all for the support.
