Grouping by the hour

I would like to bar chart a room usage count by the hour. When the room is
checked anytime during the hour it is added to the total for the hour. On the
"Y" axis is the room usage count and on the "X" axis is the hour of the day.
How should I go about doing this, considering the data below? (e.g. a bar
would extend to the point 9:00 AM and 6)

TIA for the help.

Make a pivot table of the data, with time in the row area and (sum of) usage
in the data area. Group the time field by hours:

Sum of usage
time Total
8 AM 0
9 AM 6
10 AM 3
11 AM 3
12 PM 1
1 PM 4
2 PM 2
Grand Total 19

Make a chart from this data.

I did exactly what you described, but it says, "Cannot Group That Selection"
when I attempt to group it. (I am attempting to group it by right-clicking on
the header "time" and selecting "group")

Do you know how I can resolve this? Is it the format of the time. The
datasheet that this is coming from has the cells format as the time shown in
the table.

TIA,

That is exactly the problem. It causes my data summary processes to be less
automatic (since the pivot table range is defined to an exclusing number of
rows). But, at least I am now able to group my data.

Thanks,

Hi Debra:

Thanks for the followup, I actually ran across that after the last message.
I'll be giving it a try to see if it works.

Thanks for all your help.
