1. Total sales for selected day by client (I have this done)
2. Historical average of sales for that client on the selected day of the week. For example if I select 03/11/2022 (Friday), I want to have the chart reflect the total sales for the day by client (above #1) with the historical average of sales for that client on that day of the week. I am guessing the second expression must have a combination that includes set analysis.
