Can the Fitness page training load chart be cleaned up

On the ‘Fitness’ page and the ‘Training load per day’ chart i have my google calendar enabled. I have the ‘Notes’ option enabled. This shows both notes that I’ve created (like days that I’m sick) but also a gray vertical line for each calendar entry. I want to keep my notes visible but the gray vertical lines on this chart are distracting. I still want to keep my calendar on the activities page because it helps my planning of workouts. Maybe there’s another option I can click?

Hi. I wanted to follow up on this. I might just be doing something wrong. I know i can hide individual calendar entries but is there a way to hide all calendar entries just on the fitness chart?
