When entering the trend graphs it's possible to filter/drill down based on time frames, however it's not possible to filter entire days or weeks based on 1 specific database.
The only option is to create reports with custom SQL code.
It would be nice to being able to go to the database tab, filter on a specific database to see only the load for that specific database, be it either for the entire timeframe or specific time slices.
