      So here's the solutioni need:


      1. First thing. I need the bar graph for today()-3 days. I.e. if today was 20th oct, i need the graph to be plotted for 20th, 19th and 18th. When i refresh teh data on 21st, it should automatically update. Probbably we can use datediff for this.
      2. Second thing: Along with those 3 days, i need to plot data for last week, same day. i.e. If today is 20th, i need data to plot graph for 20th,19th,18th and 13th,12th and 11th. I am not sure how to use LOOKUP formula for this.

      I have attached the sample answer i am looking for. Please note that, as the day moves forward, whenever i refresh, data should automatically refresh. Ex: If today is 21st, when i refresh, data should automatically change to 21,20,19,14,13,12.


      Tried with many things but couldnt figure out this one simple thing.


      Also it would be of great help if you can let me know some websites where i can learn tableau well.
