Count the frequency of a boolean value

Hello everyone,

 

I have a database that stores the boolean values of a field that was collected. I am trying to count the frequency that the value appears i.e. the strucutre looks something like this:

 

Element A  | Element B

True           | False

True           | False

False          | True

 

With this I would like to be able to determine that Element A is True twice and False once etc. I have been trying to use measures without much sucess or knowing the functions to use.

Hey,

 

Last night I had a brainwave and jumped out of bed and got it working using the following formula:

 

TrueCount = COUNTAX(FILTER('Table',[Element_A]=TRUE()),TRUE())

 

Thanks for the additional inputs as well, I will have a play with those other suggestions to see how else I might be able to solve the problem.

There is a simplest way to write the formula, and in my opinion, it is easy to read and understand.

 

COUNTROWS(FILTER(Table; Table[Element A] = TRUE()))

You do not need measures for this. You could do this in a table visualization by adding Element A and then Count of Element B or Count of Element A.

 

If you wanted a measure, you could do something like:

 

TrueCount = CALCULATE(COUNT([Element A]),FILTER(Table,[Element A] = "True"))

DAX is easy, CALCULATE makes DAX hard...

Shouldn't that be more something like:

 

TrueCount = Calculate(COUNTROWS('Table'),'Table'[Element A])

This assumes that Element A has only true and false values.

Well, depends on whether his true/false columns are text or boolean. You can't directly COUNT true/false columns if that's what he has. You can solve that by adding in Index field in the query and counting that instead but either method should work. And using the TRUE() function in place of "True".

Hi,

 

My scenario is something similar but I have many conditions. Like below
if category="Good" then count(Column)

else if category = "bad" then count(Column)

else if category ="neutral" then count(Column)

else

blank()

END

How do i do this?
I tried it with if and switch condition but its not working.
CheckCount =
IF([Category]="Danger",COUNT(Table1[Column1]),
IF([Category]="Bad",COUNT(Table1[Column1]),
IF([Category]="Good",COUNT(Table1[Column1]),
IF([Category]="Neutral",COUNT(Table1[Column1]),
IF([Category]="very Good",COUNT(Table1[Column1])
,BLANK())
) ) ) )

And this category is a measure which I have made. But now i just want a count of these categories so i can make some pie ot donought chart.

Thank you,
Bhavana

Worked like a charm for me! Thanks!!!
