How to remove empty rows but keep zero counts in countrows matrix?

[FabioBeka]

Hi everybody.

I have to build a matrix which shows count frequencies over 3 variables  that form a hierarchy (building-machine-sensor) on a matrix.

We need to show 0 when the combination of the 3 variables has no rows in the table of interest, but we also keep getting an empty row  when we use the countrows function.

The matrix is the one on the left  (with a card showing "4" on top).

You can see the dax function on the function toolbar on top.

Contatore Anomalie Import = COUNTROWS ( DISTINCT('Fact Anomalies Import'[VarKey]))+0

 I added the "+0" at the end to show the combinations with null frequencies, but we're also getting the empty row at the top and we can't seem to get rid of it, I also tried using VALUES function instead of DISTINCT but it was of no use.

How can we get rid of the empty row but keep the null ones?x

Please help us!

Hi @FabioBeka ,

Try

Contatore Anomalie Import =
VAR _a =
    COUNTROWS ( DISTINCT ( 'Fact Anomalies Import'[VarKey] ) )
RETURN
    IF ( ISBLANK ( _a ), 0, _a )
