Stacking Accumulated Values, Legend Split by Year in a Line Graph

Thanks Ashish. Unfortunately it didn't work. I get the same chart as above. I put the Date from my date table into the Axis as you said, the Year from the date table conditional column I had into the Legend and the PnL measure into the Values.
Just to clarify, each year should span across a year window period of time in the chart. So they should all be clumped together, and being accumulative, all be rising upwards together agains each month
