MEDIANX (

FILTER ( ALL ( 'Control tasks' ), 'Control tasks'[task_name] = currentTaskId ),

DATEDIFF ( 'Control tasks'[start_date], 'Control tasks'[end_date], MINUTE )

Hi @Anonymous ,

Create an unrelated calendar table and then you could try some DAX like this:

last_15_days = 
CALCULATE (
AVERAGE(table2[value]),
FILTER (
ALL (table2[date] ),
table2[date] <= MAX ('Table'[Date] )
&& table2[date] >= (MAX('Table'[Date])-15)
)
)

If the problem persists,could you please share the sample pbix and the result you expected?

Best Regards,
Liang
