Matrix column Subtotal

[sd_parekh]

Hi all,

My question is related to matrix visual.

Row headers : Student name ,academic year and class name

Column header: Date 

Values: Attendance Code

Refer attached image. 

I want calculate column subtotal based on attendance code "A" only .

Foe example, If date columns have three "A's" then column subtotal will display count of A. ie. 3 other wise 0.

Hi,

looks good! Just add the zero like below:

attendance code measure =
IF(
      HASONEVALUE(AttendanceDetails[AttendanceDate]),
      MIN(AttendanceStatus[AttendanceCode]),
      COUNTROWS(
         FILTER(
             AttendanceDetails,
             AttendanceDetails[AttendanceStatusId] = "2938951904584020836"
             )
      ) + IF(COUNTROWS(AttendanceDetails) > 0, 0)
  )

Ok, then you have to create a measure:

AttendeceCode Measure =
   IF(
      HASONEVALUE(table['AttendenceDate']),
      MIN(table['First AttendenceCode']),
      COUNTROWS(
         FILTER(
             table,
             table['First AttendenceCode'] = 'A'
         )
      )
    )

and use this instead of just putting "Attendance code" in your values section

Thanks. 

I wrote following measure. 

attendance code measure =

IF(

      HASONEVALUE(AttendanceDetails[AttendanceDate]),

      MIN(AttendanceStatus[AttendanceCode]),

      COUNTROWS(

         FILTER(

             AttendanceStatus,

             AttendanceStatus[AttendanceCode] = "A"

         )

      )

    )

It gives me following output. 

In column subtotal I want count of A.  Same as  second matrix last column just included for your reference.

[lukiz84]

AttendanceStatus is just the dim table right? So each of the codes is only listed once? 

You need to count the rows from AttendanceDetails, not from AttendanceStatus (Because thats always 1)

[sd_parekh]

hi, Correct.

I used below code.

attendance code measure =

IF(

      HASONEVALUE(AttendanceDetails[AttendanceDate]),

      MIN(AttendanceStatus[AttendanceCode]),

      COUNTROWS(

         FILTER(

             AttendanceDetails,

             AttendanceDetails[AttendanceStatusId] = "2938951904584020836"

             )

         )

      )

Got following result.

Thanks. 

But how can we add count 0 in rest of the values in Total Column (Column subtotal)?

I tried to put +0 outside the if statement but it broke my visual. Then after you suggestion I put it inside and it works fine as required. Thanks for you help for solving my query. 

[lukiz84]

Yes, the IF is necessary here, otherwise it would always return at least 0 - but you just want to show zero if there are ANY details 🙂 Glad i could help.

[sd_parekh]

Thanks again. 😀 . Can I ask you one more question? 

[lukiz84]

sure 🙂

[sd_parekh]

Previously in a matrix I used AttendanceCode and I used it for conditional formating for background colour.

Now we are using Measure and measure will return value in number. 

So how can we do conditional formatting using our defined measure?

for conditional formatting you need another measure now, sorry.

just create a measure with

condFormatMeasure =

SWITCH(TRUE(),

   [attendence code measure] = "A", 1,

   [attendence code measure] = "P", 2,

   [attendence code measure] = "PA", 3,

   -1

)

and use this one for the rules in conditional formatting

Hi,

Thanks for your help one more time.

Is there any way I can contact you directly if I have any question, of course with power bi community. 

[lukiz84]

sure just send me a private message anytime 🙂

[lukiz84]

So is "First AttendenceCode" a measure? If so, please share the code

[sd_parekh]

Hi, First attendance code is not a measure its column value coming from table. 

Attendance code have  "A", "P", "NRA" values. 

[sd_parekh]

In value section I used column value. Its stored in table.

I wrote "CountL2W days" dax function however power bi did not allow me to drop that measure into row section.

If I drop that function into the value section it creates group with attendance code.

Refer attached image. 

Also If I use same measure in a matrix of value section without attendance code field it shows me the correct result but I need first matrix which will have last column named  "CountL2W days" same as second matrix. 

[lukiz84]

What measure do you use in the values section?
