Jon:
The issue with that is that when I chart 11:55 pm, it needs to be below the
baseline of 1:30 am (since it occured earlier than the scheduled start time).
Just plotting 11:55 pm would put it above than the baseline.

Regards,
Jay

I think you want two more columns, one for scheduled time without the date,
so you use a formula like =A2-INT(A2), the other for actual time without the
date. These are the Y values you want.

I need to create a chart to represent the time an event is scheduled to
occur
vs when it actually occurred.

sched date/time act date/time diff comment
2/5/08 1:30 AM 2/5/08 1:45 AM 15 late start
2/6/08 1:30 AM 2/6/08 12:00 AM -90 early start
2/7/08 1:30 AM 2/6/08 11:45 PM -105 early start
2/8/08 1:30 AM 2/7/08 11:55 PM -95 early start
2/9/08 1:30 AM 2/9/08 2:00 AM 30 late start

The chart should have a static line for series 1 (scheduled) at 1:30 am
The line for series 2 should move above and below 1:30, depending on if
the
event started late (rows 1,5) or early (rows 2-4).

The best I have been able to accomplish is a chart w/x axis as dates and y
axis as the difference in minutes between scheduled start and actual
start.
The series 1 line is 0's, series 2 is a positive # (if late start) or
negative # (if early start)

But that's not what I need. I would like to y axis to display times so
that
a quick look will show, for example, the event occurred at 12:00 on day 2,
not that it occurred at -90 (minutes).

Any guidance will be appreciated.

Thanks.
