I am trying to create this calculation but got stuck for couple days and not that great on Tableau. Hoping that you guys can help quickly.
The goal to compare the sales or orders (Measure Value) between this year (ie. 3/6/2018) and last year (3/6/2017)
I looked up the thread and created parameter but for some reason the table did get populated. TY should have the same value as Measure Value, and LY should populate with last year's Measure Value
Tableau verison 10.5
Thanks in advance =)
So you have a filter on your data to only show data for three days. The filter will prevent data from year ago showing up.
Instead - check out Current vs Previous Period to Date Comparison in the Workbook & Calculation Library for a great example of doing this.
