Distribution of counts
- 7 years ago
To make this work, I believe you'll need to create a disconnected dimension table containing all possible "count" values.
Then create a Frequency measure to count the number of CUSTOMER_NUMBERs with a given count.
See for example this pbix using your sample data
I created a table called 'Count' and a measure Frequency
Count = VAR MaxCount = MAXX ( VALUES ( YourTable[CUSTOMER_NUMBER] ), CALCULATE ( COUNTROWS ( YourTable ) ) ) RETURN SELECTCOLUMNS ( GENERATESERIES ( 0, MaxCount ), "Count", [Value] )Frequency = SUMX ( 'Count', COUNTROWS ( FILTER ( VALUES ( YourTable[CUSTOMER_NUMBER] ), CALCULATE ( COUNTROWS ( YourTable ) ) = 'Count'[Count] ) ) )The Frequency measure uses SUMX to iterate over the 'Count' table so it can aggregate over multiple Count values.
You can then create visuals showing Frequency filtered by 'Count'[Count]

Thank you very much!
This works well, especially for showing the distribution over the whole range of possible counts - which can be beneficial.
(I also got it to work with a COUNT and SUMMARIZE statement, together with a bi-directional join between the 2 tables, in which case it only keeps the range of counts relevant for the selection).
