Calculate total number of True or False rows for each column

[JohnTheBig]

Hi,

I've been trying to solve an issue and I think I found a solution, however, I'm not sure it's the most efficient one.

I have a table where I have columns with True or False values.

TableA

ID	Column1	Column2	Column2
1	TRUE	FALSE	TRUE
2	FALSE	FALSE	TRUE
3	TRUE	FALSE	TRUE
4	FALSE	TRUE	FALSE

What I would like to do, is to have a vizualisations where I can check the total number of TRUE and FALSE for each column.

I though that it's possible to do it automatically in a vizualisation, however, it seems that it's not and I'm trying to solve this using DAX.

What I did was:

I created a new table.

I manually typed in True and False in the first column and then used DAX formula to populate the rest of the columns.

This is the result I got:

TableB

True_False	Column1	Column2	Column3
TRUE	2	1	3
FALSE	2	3	1

The formula I used to calculate the total number of TRUE or FALSE in table B:

Column1 = 
CALCULATE( 
    COUNTROWS( 
        TableA),
    FILTER(
        TableA,
        TableA[Column1] = TableB[True_False] )
)

I have two questions:

1) Is this the best way to do it?

2) Now I need to get for each column the percentage of TRUE values. What would be the best way to do it?

Thanks a lot!

In edit query

Change the column1,2,3 to a text data type

Click on the ID column > Transform > unpivot column > unpivot other column

Then add Dax measures

Total count = COUNTROWS('Table')

Total true = CALCULATE( [Total count], 'Table'[Value] = "TRUE" )

% = DIVIDE('Table'[Total true],'Table'[Total count])
