Transform boolean matrix into count?

Hi all,

 

I have a data set that looks like this:

DianaT_0-1595550010200.png

Is it possible for Power BI to transform the boolean matrix into something like this:

 

Grad cohort        Count

GradPre1970        0

Grad70-79            0

Grad80-89            11,882

Grad90-99            20,401

etc.

 

Your help will be greatly appreciated.

 

Cheers,

Diana

in the PQ, select count column and unpivot other columns.

then you get a new data layout

Then create a measure

Measure = CALCULATE(sum('Table'[count]),FILTER('Table','Table'[Value]="YES"))+0

@DianaT , if you want to keep them as column

 

GradPre1970 new  = if([GradPre1970] ="No",0,1)

for each column and sum up.

In matrix, you can show them on the row.

You can unpivot the data

and use replace function in power query (on right click of column) and convert no to 0 and yes to 1

Then you can do simple addition
