Your first view of your ratings will be the dashboard view.
From here, you can choose to view your ratings from the last 24 hours, last 7 days or last 4 weeks and those dates can be selected from a bar at the top of the screen.
If you have more than one outlet, you can also select which outlet or a combination of outlets from the outlet filter tab at the top of the screen.
From the pick-list at the top left of the screen, you can also choose the Today view to just look at all ratings which have been uploaded today.
Finally, you can choose the Overview option from the Report picklist at the top left of your screen.
On the Overview dashboard, this defaults to the last 7 days and you can click on the date range to choose a time period from the pick-list or choose 'custom' to input your chosen dates.
