    Hi,

    Please check the below picture and the attached pbix file.

    It is for creating a measure, and it shows by minute.

     

     

    Online time duration avg: = 
VAR _duration =
    ADDCOLUMNS (
        VALUES ( Data[Employee No] ),
        "@duration",
            DATEDIFF (
                CALCULATE ( MAXX ( FILTER ( Data, Data[Status] = "Login" ), Data[Timestamp] ) ),
                CALCULATE ( MAXX ( FILTER ( Data, Data[Status] = "Logout" ), Data[Timestamp] ) ),
                MINUTE
            )
    )
RETURN
    AVERAGEX ( _duration, [@duration] )
