I am trying to teach myself looker studio and I’m about 5 hours in and have worked out lots of the settings, watching videos and reading up along the way. I’m at a road block.

I’ve made this data on the left, the blanked out part are student names. I have created another part which isn’t shown which is a fixed-size list. I want to be able to select a single student from that and display the graph like I have done on the right but just for the one student, but each time I set it up, the x-axis becomes the score and not the year, how do I set this up? I have tried mucking around with all set up but I don’t know enough.
My spreadsheet looks like this in google sheets:

Any support would be appreciated.
