I would like to be able to utilize two or more tables in a single visualization based on the Date Hiearchy/Drilldown. One table would provide the number of unique visitors to a page for each day. Another would provide the number of unique visitors to a page for each month. Another for each Quarter. etc.
This is important for the data I'm dealing with, because summing the daily visitor numbers for each day when switching to a month view would cause severe overcounting of the number of unique visitors. A single visitor who came to the page every day in a month would be counted as ~30 visitors, rather than one unique user for that time period.
Obviously I could settle for Average instead of Sum, but preferably I need a way to make it so that when a user drills into, or out of a level in the Date Hiearchy, the visualization will change which table it actually pulls the data from. The format in each table would be identical. Each would just contain pre-aggregated daily numbers, or monthly, or quarterly, etc.
Is there any way to accomplish this?
