Operate with 2 cards

Hi everyone!   I'm having troubles while operating with 2 cards.   Both of them have filters and I have a numer from each card. Is there any way to make arithmetic operations between both cards?...

    Hey,

     

    try this

    the measure = 
DIVIDE(
  CALCULATE(
    ,COUNTROWS('yourtable')
    ,'yourtable'[colorcolumn] = "red"
  )
  ,CALCULATE(
    ,COUNTROWS('yourtable')
    ,'yourtable'[colorcolumn] = "blue"
  )
)

    Regards

    Tom

Hey,

 

unfortunately you cant't reference values from a visual (your card(s)) to calculate a new value.

 

For this reason you have create a measure that rebuilds the filter from the separate card visuals, something like this

3rd measure =
DIVIDE(
  CALCULATE(
    SUM('table'[column])
    ,'table'[filtercolumn2] = "this" &&
    ,,'table'[filtercolumn1] IN {"red", "blue"}
  )
  ,CALCULATE(
    SUM('table'[column])
    ,'table'[filtercolumn2] = "this"
  )
)

Hope this gets you started

 

Regards

Tom

Hi TomMartens thanks for the answer.

Actually what I need is to divide the COUNT of 2 things.


Example:

I've got 100 values with color red. It does not matter what is the value. It could be A, B, C, anyone.

And I've got 75 values with clor blue and yellow. Same conditions, it does not matter the value, what I need is to know how many there are.

 

After that, I need to make the division of that 2 COUNTS.

 

Is it possible?

 

Sorry for my bad English.


Kind regards.

      Hi Tom

       

      Any chance you could help me with the syntax for the following pseudo measure code (only an example as the actual data is sensitive):

       

      DIVIDE(

         CALCULATE(

             ,COUNTROWS(UNIQUE('table'[field3]))
             ,'table'[field1] <= 17

             ,'table'[field2] = "name"

         )

         CALCULATE(

             ,COUNTROWS('table')

             ,'table'[field2] = "name"

         )

      )

       

      Essentially I want to count the number of unique values in field3 where field1 is less than or equal to 17 and field2 is "name" and divide that result by the count of the number of unique values in field3 where field2 is "name".

       

      I currently have both those values in cards on my visualisation, but cannot seem to get the percentage of result 1 / result 2.

       

      Hope that makes sense.

       

      Much appreciated,

      R.

      Hi TomMartens  thank you for your answer, but what happens if red and blue values are not fixed, but ther are selected in two different selection box?

       

      Is any option to do the same dinamically?

       

      Thank you
