Tracking year by year changes

Hi all

I have a simple line graph that is looking at an average premium amount per month for the last 48 calender months (01/07/2018 - 30/06/2022)

 

 

I now need to create a second visual that tracks the year on year change in the average monthly premium. For example,
((June 2022 avg prem) / (June 2021 avg prem)) - 1

I don't know how to achieve this in a measure, hoping someone can assist.

 

Many thanks!

    HB13 , Create a date table, Join with date of your date table, create MOM measure like the below examples and use that on secondary line axis

     

    MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
    last MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],-1,MONTH)))
    last month Sales = CALCULATE(SUM(Sales[Sales Amount]),previousmonth('Date'[Date]))

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

      This helps with month on month changes but I need to calculate a Year on Year change for the (last 48) months that are being filtered for

    Hi HB13 ,

     

    Please try:

    Add a new column to calculate the changes:

    Column =

var _a =CALCULATE(MAX('Table'[Value]),FILTER('Table',YEAR([Date])=YEAR(EARLIER('Table'[Date]))-1&&MONTH([Date])=MONTH(EARLIER('Table'[Date]))))

return IF(ISBLANK(_a),BLANK(),CALCULATE(MAX('Table'[Value]),FILTER('Table',[Date]=EARLIER('Table'[Date])))/ _a-1)

    Then create a date table and create relationship between the two tables:

     

    Apply date and the column to the line chart:

     

    Final output:
