Hello everyone

I have a question.

It turns out that one of Perspective's DEMO applications has as an example an app called "Water Treatment", which is achieved by pressing on a symbol marked in red in the following photo, bringing a specific tag to the historian in a PopUp or in another pop-up window.

I want to do this same thing in Vision with Easy Chart, but it doesn't work.

Testing the Easy Chart from ignition designer, it works well if I assign a tag to it from the editor manually, but I have not been able to pass the parameters to be graphed from a script activated by a button from the same screen, much less from another that opens the container of that easy chart.

The button you see has this logic:

I have also tried from another screen, opening that one:

but it doesn't carry anything.

The graph works fine with the same tag if I place it manually,

but I want to use a single screen to show different tags or combinations of tags depending on what is pressed on another screen, like the DEMO in Perspective, is that possible?

It won't let me upload more than 3 photos so here is the complete question:

Beforehand thank you very much

In Vision, complex properties are Datasets. You must create a dataset object with the pen information desired (all necessary columns) and assign that to `.pens` and/or `.tagPens`. (Not inside the configureChart extension.)
