I have a line chart of "sum(Sales)" as an expression and two dimensions:
primary dim is "month" and secondary dim is stores (i have only 3 stores).
the chart im getting is sum of sales per month and for each store there is a different line.
i tried to use "Above" to create a delta chart but it didn't work. it worked only with chart having only one dim (month) but i guess that since there are 2 dims - the "Above" function doesn't know to wich "Above" to reffer to.
