Previous Curren Next weeks data in one chart

Hello everyone!

I have a task to get data for previous 4 week, current week, and next 4 week in one chart.

I've tried to solve this task, but it instead of current week returns today()'s day in calculates previos 4 week and next 4 week

It's my decision for this task. But there didn't show next weeks because for next week data no data available
 I've created a new table for data and create column with true/false values:
Plus / min 1 month = IF(
IF('NEXT DATE'[Date] > SELECTEDVALUE('Календарь'[Дата]) , 0 - DATEDIFF(TODAY() , 'NEXT DATE'[Date], MONTH),DATEDIFF('NEXT DATE'[Date],TODAY(),MONTH))
<= 1 &&
IF('NEXT DATE'[Date] > TODAY() , 0 - DATEDIFF(TODAY(),'NEXT DATE'[Date],MONTH),DATEDIFF('NEXT DATE'[Date],TODAY(),MONTH))
>=-1,TRUE,FALSE)

Can you help me to solve this task?


Thank you!!!
