Operate with 2 cards

[chrisgehm]

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?

Example:

Card1

100

Card2

75

What I need:

100/75 = 1.33

Kind regards!

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.

Hey,

try this

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

Regards

@TomMartens Do you know why I'm getting this error?

Hi Tom

Thanks for this. I've spent too long trying to get this result until I found your messaure!

One thing, for me the mesaure only worked when I took out the commas (in Red below): 

the measure =
DIVIDE(
CALCULATE(
,COUNTROWS('Table20')
,'Table20'[Status Fixed] = "Disengaged"
)
,CALCULATE(
COUNTROWS('Schedule20')
,'Table20'[Status Fixed] <> BLANK()
)
)*100

Any thoughts why this might be? 

Thanks

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

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.
