I see; it helped when I formatted the times as numbers. The formula adds one
to times after midnight so that 1:45 am goes from .729 to 1.729, while times
before midnight remain as is, 11:45 pm is .9896. So times after midnight are
always greater and plot above the pre-midnight times. Excellent.

Thanks for all your time.

You get back your original time values, not your original date-time values.
The values I calculated range from noon on day zero to noon on day 1, so
midnight is at 50% of the range. This allows 12:15 to be plotted above 1:45
by 30 minutes, not below it by 23:30.

Thanks for the formula, but I just get back my actual time. Am I doing
something wrong?

Reducing my problem to a simpler question, how would I plot 3 times, say
11:45 pm, 12:00 am and 12:15 am., where 11:45 pm would show up below
12:00am


12:15am .X
12:00am .........X
11:45pm.................X
..............day1 day2 day3


I am working only with hours/minutes, I am not charting the dates. (If I
did, my baseline of 1:30 am would not be a flat line, it would climb,
since
the date portion of the number is increasing).

Thanks and Regards,
Jay

Thanks for the suggestions, but I'm still stuck.

I'd like the hours to be the y axis and the dates to be the x axis,

2:00 am
1:00 am
12:00 am
11:00 pm
10:00 pm
2/5 2/6 2/7 etc

My problem arises because I want time prior to 12:00am to be
"negative",
in
that it plots below 12am

Thanks

Regards,

I don't think that helps, does it, Jon?
11:55 PM would come out as nearly 1.5, whereas 1:30 AM would be just
above
0.5.
You could get what I think you're looking for by using =MOD(A2+0.5,1),
but
then you would get the same problem either side of mid-day that you're
currently seeing around midnight.

Oh right. How about =A2-INT(A2)+0.5, which puts midnight at a value
of
0.5?

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.

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.
