How remove measure from matrix or chart by using the slicer?

[Determistic]

I have created slicer where end user can choose the measure what he/she want to see. My solution is that kind:

1.  I have created four separated measure like these:  

ACT+LE =

 var logictest =

COUNTROWS(DISTINCT(

    FILTER(

        ALLSELECTED(Param_Selection[Measure]),

        Param_Selection[Measure]="ACT+LE")

        ))=1

        Return

        IF ( logictest,

        [ACT + LE],BLANK())

Prev Year. =

 var logictest =

COUNTROWS(DISTINCT(

    FILTER(

        ALLSELECTED(Param_Selection[Measure]),

        Param_Selection[Measure]="Prev Year")

        ))=1

        Return

        IF ( logictest,

        [Prev Year],BLANK())

2. Then I have put these measure on matrix table values

3. The end goal is to get rid off unselected measures from slicers

How to do that?

@Determistic Maybe construct your measures so that they check the selection and under the right circumstances return BLANK() instead of a value?

Thank you for answer. I don't get your point. Iam already returning blank() after locigal test.
