I’m trying to create a chart that displays the distribution of the number of cases per customer (50% have 1 open case, 20% have 2 open cases, etc.). I have an Aggregate Composite on the Customer Object that is the Count of Case IDs (the field is Base Object → Case → ID), but I am unable to select this in the Grouped Field dropdown of the Quick Chart. Is it possible to group by an aggregate in this way?
