% of Column total

[Anonymous]

I have two matrixs This Year and Last Year, and % of Column total for This year and % of Column total for Last year

Currently i use " Show Value as - Precent of colume total" , but i need to compare this year vs last year. 

Anyone know the DAX for that? 

Thank you!

Hi @Anonymous ,

I’ve created a table with the different sales by years, figuring that you’d like to get the % of Total sales for 2017&2018, which shown as below:

% of TotalSales = DIVIDE(SUM(Table1[Sales]),CALCULATE(SUM(Table1[Sales]),ALL(Table1)))

And the comparison result could be generated like this:

Diff % = CALCULATE([% of TotalSales],Table1[Year]=2018)-CALCULATE([% of TotalSales],Table1[Year]=2017)

Plz correct me if I misunderstood something.
