I believe i got it to work!
Code:
'build table for graph
strSQL_table = strSQL_table & strSQL2
'build record source for subform
strSQL_subform = strSQL1 & strSQL2
'update the subform
Me.sub_TempSched.Form.RecordSource = strSQL_subform
DoCmd.RunSQL strSQL_table
'requering the graph so it's redrawn with current data
Me.OLEUnbound_DayGraph.Requery
Now the only problem i have to correct is that my first row of data is missing in my graph (header line assumed???)
just an FYI
