Strange Spike in Line Chart when using Rolling Year Formula.

 there is a strange Spike at the End of a Line Chart when using a Rolling Year Formula and going Down to any Level on the Chart below Years. I've tried

1 Adjusting the X Axis to filter days Before Current Date.

2) Using a date Filter  for the Visual based on final date in Data Set. Ive Never had a problem with this in Excel (i.e  Rolling- year formula, at a MM_YYYY level this is the Rolling year Formula I am using:

MIC_RY1_all = CALCULATE(Sum(FACT_MIC[Units]),DATESBETWEEN(DATE_DIM[Date],NEXTDAY(SAMEPERIODLASTYEAR(LASTDATE(DATE_DIM[Date]))),LASTDATE(DATE_DIM[DATE])))

 Rolling Year at a QQYY level:

At a Year level , no spike:

 

 

Rolling year formula at a sub-year level in Excel ( No issue )

        Yes thank you for the Tip, which seems obvious to me now. I have a Calendar table called DATE_DIM but I didn't specfically designate it as a Calendar Table. This solved the Spike problem. thank you!
