Get the count of a category in a time interval

[tc5613213]

Hi all, this is the relationship that I just drag to a workpage. Is there any way that I can get the number of ocurrence of each category (i.e. column 3) to get some thing like:

column1           column 2           column 3
20/04/2016       12:00:00 AM      Residence: (count)

                                                    Business affairs: (count)
Anyone can provide some hint? Thanks
