I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

The Datetime data type represents a point in time on a specific date.  It should not be used to store elapsed time.  I don't really understand your question so please give us more information.

If you data are of data type Date, then minutes are extracted easily:

=Minute([YourFieldName])

Open in new window

or, if it is a count of minutes from zero (Midnight):

=DateDiff("n", #00:00#, [YourFieldName])

Open in new window

To exclude a date part from your values:

=DateDiff("n", #00:00#, TimeValue([YourFieldName]))

Open in new window

If the time part of the field is  2:24 which would be a point in time, you get 24 as the minutes value.  If you are using this as elapsed time, you will want 120 + 24 so that would make the expression:

(Hour(YourDate) * 60) + Minute(YourDate)

If the field accumulates more than 24 hours, then you need to convert the "days" also

But a Pat requested ...we still need to know a lot more about your data, ...and the format of the chart.

Please post an example/sample of your data, and also post a clear graphical example of the output you are looking for (based on the sample data)
