Slicer Week/Month formula

[Anonymous]

Hi all,

Could you please help me with a dax formula, which I can use for Chliclet Slicer connected to a lince chart. The slicer has 4 options: 1 week, 2 weeks, 3 weeks, 1month. If 1 week is selected it should show the last 7 days including today, the 2 weeks option should show the last 14 days including today, 3 weeks -  the last 21 days incl.today, and 1 month- the last month incl.today. The dates should changing dynamically. 

I used this statement for 1 week: SWITCH (TRUE (),DATEDIFF ( 'date'[table], TODAY (), DAY ) <= 7, "1 Week",

DATEDIFF ( 'date'[table], TODAY (), DAY ) > 7 and it works, but for the 2 weeks,3w,1month- the logic isn't working.

Thank you.

I would have you measure only return values within the specified range, so

VAR __MinDate =
SWITCH([Slicer],
"1 Week",TODAY() - 7,
"2 Weeks",TODAY() - 14,
...
)
VAR __Date = MAX([Date])
RETURN
IF(__Date >= __MinDate,[measure calc],BLANK())

Hi @Greg_Deckler 

Thank you for the formula and apologies for the delayed response. I tried the formula and it works, but the result is not what I’m exactly looking for. Currently with the suggested formula if I selected the slicer option for 1 week I get the dates for the last seven days (26 of May – 3rd of June). If I choose “2 weeks” (14 days) it returns the week 14days ago (20-26 of May). I need when I select the slicer option for "2 weeks" to visualize the whole period starting 14 days ago until today (20 of May – 3rd of June).

Is there is a way to do that and to changing the dates dynamically. Or do you have an idea is it possible to have a slicer option which to combine the results for the 1 week and the second week values.

Thank you.
