Hello Jamie Vinnell,
Is the source data for this issue in this format or do you have actual sales numbers associated with date fields? I ask because using the detailed data and then using Tableau to aggregate the data to the level of year/store would be easy. Using pre-aggregated data in this format will provide limited functionality. If possible, please provide a Tableau Packaged workbook with sample data that mimics the source data. This will enable the community to assist with potential options.
