如何在 Power BI 中按行小计过滤矩阵？

Question

I have a matrix that shows flight data and travellers names, with totals to show how many passengers are on each flight. I need to be able to filter this table down by the row totals so that only those with 2+ travellers are shown, but I cannot figure out how to do so since the count will always show as 1 for each line.

Answer 1

When you use a matrix visual and show the count of travelers, it is essentially an implied measure. You can't place a measure in a filter because the calculation will vary depending on the context of the visual.

You can create a calculated table that summarizes the flight data. You can then use the "Travelers" field from this new table in a numeric filter.

Summary Table = SUMMARIZE(Flights,Flights[Flight Number], "Travelers", Count(Flights[Traveler]))

Answer 2

While the calculated table provides the expected results, it won't inherit filter context from the visual so this solution. Best solution is below.

Passenger Per Flight Filter = 
IF(
   [Passenger per Flight] <> BLANK(),
   CALCULATE( [Passenger per Flight], ALL( 'Dim Traveller' ) ),
   BLANK()
)
