Daily YoY % Change Line Graph

Hello!

I am very new to Power BI and need some help with the line graphs. I am ultimately trying to create a line graph that shows the YoY % change per day (based on the date slicer) for various domains/website groups. 

Every time I create the chart, it is not working, and honestly, I am unsure what to do! I have YoY% built out already, and it works perfectly in a matrix/table. but does not work with line graphs. This is what I'm getting:

Ultimately, I am trying to achieve this view (from the tableau report), that automatically updates any time the date slicer is changed.

Any help is appreciated!
