Date Range based on Slicer selection

[ragnezza]

Hello - I'm looking to return a list of the previous "X" days based on a selected day from a slicer.

For example, once a day is selected in the 'Date' slicer, I want to return the date range in the visualization for the previous 180 days up to the selected day.

In simple words, the logic would be something like the below, but I cannot make it work:
IF ( Date >= SELECTEDVALUE ( Date )-180 || Date <= SELECTEDVALUE ( Date ) , Date , blank() ) 

And then use 'Date' in the visualization and exclude blanks.

Any recommendation is more than welcome, thanks!!

Thanks @DataNinja777 . Your solutions provided a cumulative count for the last "X" days, while I was looking to include/exclude days based on the selection. I made it work with the following Measure and by adding a separate Table with just the 'Date' field, which is used as filter.

Measure_last_180_days = 

IF (SELECTEDVALUE('Date'[Date])-180 <= MAX( 'Main Table'[Date]) &&

SELECTEDVALUE('Date'[Date]) >= MAX('Main Table'[Date]),"yes","no" )

Thanks @DataNinja777 , this can help as it outputs the [Daily trends] for the previous 180 days, but it doesn't have any relation with the SELECTEDVALUE.
Below are two examples of how I would like this visualization to show based on the selected dates:

thanks!

Hi @ragnezza ,

What about like below?

Thanks @DataNinja777 . This can work if I want to have the cumulative "Daily Trends" up to the selected day.
For this purpose I find this other solution:

Measure =
if( MAX( 'Main_Table'[Date]) >= SELECTEDVALUE('Date'[Date],min('Date'[Date]) )-180 &&
MAX( 'Main_Table'[Date]) <= SELECTEDVALUE('Date'[Date],max('Date'[Date]) ),
"Yes", "No" )

And then use this 'Measure' as a filter in the visualization.

Hi @ragnezza,

What about using DATESINPERIOD function?
