Measure or count in Y Axis

nonoFRissy85,

Ah thanks, now I get it. I have a possible way how you could present this in a bar chart (not sure if this is the most optimal method).  

1. Add a parameter table to your model.
   
2. Place the parameter column on the y-axis. This column refers to the number of different products (1, 2, 3, etc)
3. Create a new measure, where you count the number of stores for every number of different products it sells.

Nb of stores =
COUNTROWS (
    FILTER (
        DISTINCT ( 'Table'[Store] ),
        VAR _store = 'Table'[Store]
        VAR _product =
            SELECTEDVALUE ( Parameter[Parameter] )
        VAR _products =
            CALCULATE (
                DISTINCTCOUNT ( 'Table'[Product] ),
                REMOVEFILTERS ( 'Table' ),
                'Table'[Store] = _store
            )
        VAR _result = _products = _product
        RETURN
            _result
    )
)
​

Place the measure on the x-axis and this is your result:
