I have a Chart.js graph with the following HTML, embedded in a dynamic page . I'd like to export values filtered in the page to the graph.

myChart

SO you have to replace the data: [8, 10, 5, 10, 13, 25, 4.5] and use a variable instead, and post the data to the iframe.
Yisrael has already published an example how to do it. Search the forum.

Tks J.D.
I’ve searched already but I’ll do it again.
Could you send here the link of Yisrael’s post in case you have it?

@jonatandor35 Tks again.
It look far more sofisticated than what I need but I’ll ready it carefully.

The example is indeed classified there as “advanced” , but it’s not really complicated. I’d classify it as “intermediate”.
