title: Tableau - Current year, moving average and previous year figures, for the last 2 months
body: <p>I've exhausted my creativity... so here I am. I need to create a line graph showing daily figures of the last two months from today of:
  - this year sales
  - this year moving average sales
  - previous year moving average sales</p>
  
  <p>It seems pretty straightforward, but I tried all i could and was not able to find the right filter/data combination. Can anybody help me with that, please?
  Thanks</p>
