I have no idea if this is possible and I have been pottering about forums but haven't come across anything that works.
I have this data, which if plotted into a table visual shows me this:
I want to create two KPI tiles or Cards: one that says the current week's delta and one that says the previous week's delta. I'm assuming I want to create a new measure like 'Current Delta' which filters my Delta measure.
All of the columns in this table are measures besides the Week Number column which comes from my Date Table.
