Column chart to show difference %

spartanboy , I such we need measures like

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))


last year MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-12,MONTH)))
Previous year Month Sales = CALCULATE(SUM(Sales[Sales Amount]),previousmonth(dateadd('Date'[Date],-11,MONTH)))
last year MTD (complete) Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(ENDOFMONTH(dateadd('Date'[Date],-12,MONTH))))

diff = [MTD Sales]-[last year MTD Sales ]
diff % = divide([MTD Sales]-[last year MTD Sales],[last year MTD Sales])

If need you can put all three into a calculation group
