You are not stating the exact "Graphical" Output you are seeking.
My guess is that you want to see a unique list of all used dates and along with each of these dates you want to see the associated Topics, Cases, ...etc
I am not sure that Access can represent the query you are after, but this can easily be done with a Report and two subreports.
The Main Report being the list of unique, used dates
The two subreports being the Cases and Topics tables respectively.
The subreports are linked on the unique date to their corresponding dates.
Here is a sample.
The Report is named: rptDatesCasesTopics
If this is what you wanted, I am sure that you can modify it to fit your needs.
