Tracking year by year changes

[HB13]

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!

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:

@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])

Thank you for your response, much appreciated 😄
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
