I try to explain better what I would like to accomplish: from the browser console I can access the `div` of the CWC that I'm working on with the following code: const div = document.getElementsByTagName('iframe')[0].contentDocument.getElementById('plotly-graph'); Then I can access his properties with: div.layout.traces div.layout.shapes div.layout.annotations Is it possible to do the same from the scripts in TIA Portal? I've tried something like the following code, but without success: Screen.FindItem('Plotly').div Thanks!

The basic information are available in: https://support.industry.siemens.com/cs/de/en/view/109794040 Bye Murof
