New to reporting services, need help doing a report that shows PC logins by the Hour

Hi all,

I'm new to reporting services and i'd appreciate some help with this Reporting Services report.

Data on PC logins and logouts are captured in an SQL Table. The login date and time is in 1 field, as is other fields like IP address, Hostname etc.

I've been tasked with creating a couple of reports that allow the user to select a Start_Date and End_Date, then choose a Room, and then display a report that shows the Total number of logins by each HOUR (24 hours) in each Room.

i.e. Room A101        Number of PC logins          

00:00                       20          

01:00                       15          

......                           ......          

23:00                       1

Can anyone please help me with a step by step on how to achieve this? As a new user of reporting services, I've learn how to do a report by using the filter between the dates, but I have no idea how to get the times displays as mentioned above.

Thanks
