I'm having a problem with a line chart. Is my Measure incorrect?

[PrivateAnalytic]

Hello all! I'm reaching out because I have created a measure which shows the total amount of people enrolled in something divided by the amount of users there are, which is showed in a percentage. My total number makes complete sense to me (Which is the one boxed on the right), however the line chart doesn't really make much sense to me. Is my calculation wrong? Or am I doing something wrong?
