How to Organize Data - Same Date Multiple Categories

I have email lists that I collect the number of subscribers for each day. I would like to put this into Power Bi Desktop to visulize. I would like to have one line graph charting all the lists over time. However, I would like to have 2 slicers; one for the time frame I want to look at and one for the email list(s) I want to chart.

What it the best way to setup this data to be able to accomplish this? Thank you for your help.
