How do I divide two columns that are grouped? The Revenue Column is taking the sum of all revenue for each D9-THC bucket. The same applies to the Quantity Sold Column. However, the Days column takes the distinct count of days where these products were sold. I would like to create a new column "Revenue Per day" that divides revenue by the days column. How can I do this while retaining the ability to filter by date, and have all my values and the newly calculated field change?
