Graph is not showing full two hours worth of requested data

[MFS]

I hope this is an easy one . . . .

My graphs are not showing the full amount of time that I am requesting in my queries criteria.
In other words I've asked to show data from lets say 8:00am to 10:00am. The graph shows 8:00am to 9:45am.
What could be causing this????

If your query pulls all data from this limit...then you have no record at exactly 10am. (945 is your last datum)

To show a 10am that isnt there, you need an 'empty' record. Modify your query to add the min rec (8am) and max record (10am).
I use a union query, 1 query has the max/min records, and union with 1 query with my real data.
That way the entire range is given in the data.

That's the thing, I do have data for 10:00 am.
I write my query criteria in textboxes on a form, in this case . . .
Beginning time = 8:00am (Text100)
End Time = 10:00am (Text101)
I then hit an 'ENTER" command button which populates a form with a graph and a subform.
The subform shows all the data from 8:00-10:00 but the graph only shows from 8:00 to 9:45.
The 9:45 time is not always off by 15 minutes, the graph may on some occasions only be off by 4 minutes.
