Sum a total per hour

[skiabox]

I have two columns.
The one column has a total field from a table and the other has a time only(not date) field taken from another field of the same table.
I made a sorting by the time field and it begins the sorting after midnight 00:00 and it arrives at 23:59 or something like that(it is a sorting of a day).
Is there any way I can get the totals per hour?
Thank you!

Ok.I've done it!
I made a grouping over that sorted time field by hour and then I simply entered a summary in the group footer!
