I am attempting to see what's possible in generating selection categories via Arcade in a dashboard. I am stuck right at the start as there are no profile variables available when opening the expression screen. I have a list element already added to this dashboard which references a stand-alone table. In the list element itself, I was able to construct Arcade expressions against the table as the profile variable as $datapoint. I am not finding any specific guidance for Arcade in selection categories (perhaps it's bad googling?). Has anyone navigated this before?
