    In the Allexcepted put the column date that your are using in the charte.

    Allexcepted will remove all filter on that table except on the column you mention, so I think it Could solve your problem.

    Try...

cw900,

See if this solve your problem:


Measures:

SimpleAvg = 
AVERAGE (T_Logins[Total])

New Avg = 
IF(
    NOT(ISBLANK([Count of Logins])),
    CALCULATE(
            [SimpleAvg],
            REMOVEFILTERS(T_Logins[Student]),
            T_Logins[Event_Type]="Login"
    )
)

Ok that is much closer. I changed the measure to this:

New Avg v2 =
    CALCULATE(
            AVERAGE (CourseData[Total]),
            CourseData[Event_Type]="Login",
            REMOVEFILTERS(CourseData[Student])
    )
 
This works in the example here but when I apply this to my real data it doesn't work. I think because my real table contains many other fields other than Student_Course_Name.
 
Is there any way in that measure to say only calculate the average based on Student_Course_Name?

    Try something using Allexcepted.

    DAX is all about context and for that reason is important to have the right example.

    In my example is working fine on my side...

    Hmmm. ALLEXCEPT looks useful but I'm struggling to work out the implementation.

     

    The following measure just gives me the same average on each date.

     

    New Avg v3 =
        CALCULATE(
                AVERAGE (CourseData[Total]),
                CourseData[Event_Type]="Login",
                ALLEXCEPT(CourseData, CourseData[Student_Course_Name])
        )
