Spreadsheet task (Chart Creation):
Create a dynamic summary section in the “Forecasting Summary Data” sheet that first includes a drop-down list for selecting the Service Area, defaulting to 'B'. Use this selection to automatically generate two summary tables: one showing the 4 quarterly values (Quarter) and another showing cumulative values (Quarter (Cum)) for Blue, Green, Blue & Green, and Original, by summarizing the main dataset. Ensure the tables update based on the selected Service Area and exclude totals or blank rows. Then, create two linked line charts from these tables: a “By Quarter” chart plotting the four series against Qtr 1-4, and a “Cumulative” chart plotting the cumulative values over the same quarters. Format both charts in £ currency, include legends, use line charts with markers, place the quarterly chart above the cumulative chart, and ensure all tables and charts update automatically when the Service Area selection changes.
