All,

I don't know if this is possible, but here goes.

I have a number of entries in a spreadsheet, showing me date / time of
access and a site. For example:

01-07-2008 09:15:34 Aberdeen
01-07-2008 09:15:37 Aberdeen
01-07-2008 10:10:10 Glasgow
etc.

What I need to show is a graph that lists the number of users, per
site and per hour that accessed the system. So, in the above example,
two columns / entries would be shown on the graph with Aberdeen having
a count of 2 for the period 09:00 until 09:59 and Glasgow showing 0.

Then, in the second column, Aberdeen would show 0 for the period 10:00
until 10:59 and Glasgow would show one.

Is this possible?

TIA

Duncs
