in case I have 2 unrelated tables can I create a chart with dimensions from one table and data from another table?
What I want to have is a chart with the Product field as a dimension and sum(Registrations) as an expression. Actually, it is Segment that I would like as a dimension, but that's already a secondary problem.
My idea was to create an expression like this:
but none of these seem to be even close to the working version. However, apart from the dollar-sign expansion the expression Only(Product) works well in the chart.
