I'm new to tableau. I have a workbook showing sales analysis monthly. The result is something like below, and the user can choose the range of time period like last 3 months/previous month/last year etc.
My question is, how do I consolidate the results to show a total at first then the user could have a "+" sign to drill down the data into each month?
And the consolidate range should based on the date range the the user selected.
Could you provide a packaged workbook showing what you're tried so we can take a look and try to find a solution?
