I cannot seem to figure out how to trend year over year by month in the workspace. I'm just trying to get our key metrics (unique visitors, visits) for this year to date by month and then how that compares to last year the same time. Should I just do two freeform tables next to each other? seems odd that this is not an easy option unless I am completely missing it.
UPDATE: based on a post I discovered by accident from November it sounds like this is still on the docket for improvements. I'm kind of shocked it was pushed without this. I really thought I was just missing something.
Have you been able to create the comparison in workspace?
For a comparing trended reports like the key metrics report you would have to create 2 different freeform tables and use different date ranges. For comparing a ranked report like a pages report you would simply have to add the metrics/dimension twice in the freeform table and apply the date range on individual columns.
I can't get the Compare Time Periods feature to work at all. I have a freeform table with a PageName value as the row, and Visits as the metric. When I right click on the PageName value I don't see Compare Time Periods as an option.
This isn't actually a great solution as there's real physical distance between the two. There's a compare option within Reports that should be available on on reports, not just custom traffic and conversion reports or when added to dashboards.
