    Omg got it! Here's the formula for anyone else that comes across this.

     

    CALCULATE(
    COUNTA('Report'[Notice Number]),
    DATESBETWEEN(
    AxisDateTable[Date],
    SAMEPERIODLASTYEAR(
    LASTDATE(AxisDateTable[Date])
    ),
    LASTDATE(AxisDateTable[Date])
    )
    )

I'm still struggling with this one. I think I need some variation of this?

 

Count of Notice Number total for MonthYear =

CALCULATE(

COUNTA('Report'[Notice Number]),
FILTER(
ALLSELECTED('Report'),
format('Report'[Lodged Date], "YYYYMM") < FORMAT(MAX('Report'[Lodged Date]), "YYYYMM")
&&
format('Report'[Lodged Date], "YYYYMM") >= format(EDATE('Report'[Lodged Date],-12), "YYYYMM")
)
)
 
But can't get it to display anything. And when it does, it's not even close.
My thinking is my measure needs to look at the Report table while repecting the filter on the [DataDate] column set by 'DataDateFilter'[MonthYear].
Then, for each month on my axis, it needs to count -12 months to current axis month.
 
I'm just struggling to get anything that's rolling though. Everything comes out running total 0 to current :S
