Create Column - Previous Year (Dax or Power Query)

I have a base with 3 years of history and I would like to create a column with the same period of the previous year... Aiming to hit line by line (of the same date), without having to place the date column in the visual (the same table).

 

 

In short, it is taking the date without losing this mapping between the same dates and dates.

Can you help me with the best procedure to do creating this column? 

 

Thanks!

    DouglasRoubaud  you can create a measure to calc previous year value like below

     

    Value_LY = CALCULATE(SUM('Table'[value]),DATEADD('Table'[date],-1,DAY))
     
    and then create your visual like below
