However, when I add a page level filter that is one single date, my measure returns only values for that date - my line chart becomes a single dot! So does the page level filter override ALL? Is there a way around this?
@Jamie You will have to create a date table that is not connected to the model, and use the date from this disconnected table in slicers or filter pane.
Sales YTD =
VAR DisconnectedMaxDate =
MAX ( DisconnecteddimDate[TheDate] )
RETURN
CALCULATE (
SUM ( factSales[Actual] ),
FILTER (
ALL ( dimDate ),
dimDate[Fiscal Year] = SELECTEDVALUE ( dimDate[Fiscal Year] )
&& dimDate[TheDate] <= DisconnectedMaxDate
)
)
