Sets are custom fields that define a subset of data and they can be used to compare subsets of data.
This visualization is comparing sales for (a) one sub-category, (b) sub-category cohort, and (c) all sub-categories. The steps to create the calculations are:
1) Create a set for sub-category, a set for sub-category cohort, and a set for all sub-categories.
2) Create formulas to calculate for sales based on each set.
@Sales (Sub-Category)
if [Sub-Category Set] then [Sales] end
@Sales (Sub-Category Cohort)
if [Sub-Category Cohort Set] then [Sales] end
@Sales (All Sub-Categories)
if [All Sub-Category Set] then [Sales] end
3) Use these formulas to create a line chart for data comparison among the sets.
4) Show sets for users to select a member for Sub-Category Set or members for Sub-Category Cohort Set.
