I am looking to create aliases which are dynamic. I read a few links but since i am a newbie to tableau in fact newbie to Business Intelligence and data visualization. I didn't understand half the things the posts mentioned. So here is the thing that I want:
I need to create a graph which shows sales and profit for the period of 2 months. So the aliases that I need to show is like this
Present Week, Previous Week, Previous Week-1 and so on. How to achieve this. I thought of comparing the present date, but couldn't figure out how to add it to week and then display it. Please explain in as much detail as possible.
