是否可以计算Tableau中计算字段结果出现的次数？

Question

I have a function that categorizes calls a user has made into 3 categories using this calculation:

    IF 0 <= DATEDIFF('dayofyear', [SubmittedDateTime], [CALLDATE]) 
    AND DATEDIFF('dayofyear', [SubmittedDateTime], [CALLDATE]) <= 7 
    THEN "Week After"
    ELSEIF -7 <= DATEDIFF('dayofyear', [SubmittedDateTime], [CALLDATE]) 
    AND DATEDIFF('dayofyear', [SubmittedDateTime], [CALLDATE]) < 0
    THEN "Week Before"
    ELSE "Not within a week"
    END

I was wondering if it's possible to count the number of occurrences of a particular outcome of the function on a per user basis in order to then categorize each user based off of the number of occurrences. I'm attempting to use this calculation to do so:

    IF { FIXED [SUBID]: COUNT([DateDiff Calc] = 'Week After')} = 1
    THEN "1 Conference User"
    ELSEIF { FIXED [SUBID]: COUNT([DateDiff Calc] = 'Week After') } > 1
    THEN "Multiple Conference User"
    ELSE "0 Conference User"
    END

but the COUNT function I'm using is not working properly it seems. It seems that the COUNT function is also counting occurrences of both "Week Before" and "Not within a week" from the first function.

I think the problem is the measure part of your LOD expression :

 COUNT([DateDiff Calc] = 'Week After')

This will just give you count of both times: when your conditions is met and when its not met. [DateDiff Calc] = 'Week After' will return true or false, both will be counted as +1 in the count function.

You could try something like:

IF { FIXED [SUBID]: SUM(IF[DateDiff Calc] = 'Week After' THEN 1 ELSE 0 END)} = 1 
THEN "1 Conference User"
