Filter table based on date slicer, but one fieldname need to show last 3 months too

[Krexx]

Hello, i want to show sales of cars based on dateslicer. But for one brand i want to show also the last 3 months. 
My table contains three columns - For example: 

Type	Brand	Date
Car	BMW	01-01-2020
Car	Mercedes	02-03-2020

Now i would like to count all the types based on the brand and show it in a barchart. But for BMW they should also display the last 3 months based on the date slicer. When i choose 01/01/2020 - 31/12/2021, then it should display also data for BMW from 01/10/2019. Here is an example what i would like to achieve: 


Thanks in advance

Hi @Krexx 

I build a  table like yours to have a test.

Firstly, you need to build a calendar table.

Date = CALENDARAUTO()

Use calendar table to build a Slicer.

Then build a measure to achieve your goal.

Measure = 
VAR _MinDate =
    MINX ( 'Date', 'Date'[Date] )
VAR _MaxDate =
    MAXX ( 'Date', 'Date'[Date] )
VAR _Last3Month =
    EOMONTH ( _MinDate, -4 ) + 1
RETURN
    SUMX (
        'Table',
        IF (
            MAX ( 'Table'[Brand] ) = "BMW"
                && MAX ( 'Table'[Date] ) >= _Last3Month
                && MAX ( 'Table'[Date] ) <= _MaxDate,
            1,
            IF (
                MAX ( 'Table'[Brand] ) = "Mercedes"
                    && MAX ( 'Table'[Date] ) >= _MinDate
                    && MAX ( 'Table'[Date] ) <= _MaxDate,
                1,
                0
            )
        )
    )

Build a Clustered column chart and the result is as below.

Default:

Change the slicer between 2020/01/01 and 2020/12/31.

@Krexx - Sorry, having trouble following, can you post sample data as text and expected output?

Maybe Complex Selector? https://community.powerbi.com/t5/Quick-Measures-Gallery/The-Complex-Selector/m-p/1116633#M534

Not really enough information to go on, please first check if your issue is a common issue listed here: https://community.powerbi.com/t5/Community-Blog/Before-You-Post-Read-This/ba-p/1116882

Also, please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490

The most important parts are:
1. Sample data as text, use the table tool in the editing bar
2. Expected output from sample data
3. Explanation in words of how to get from 1. to 2.

@Krexx , not very clear

You can use rolling 3

Rolling 3 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],ENDOFMONTH(Sales[Sales Date]),-3,MONTH))
Rolling 3 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX(Sales[Sales Date]),-3,MONTH))
Rolling 3 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-3,MONTH))

or this approach
