You need to have at least four times listed for a specific event in order for a progress graph to show on your profile.
If you don’t have enough times. All you need to do is add them by clicking on the “Meets” tab. Add your past meets & times here. Don't worry if they're slower than your best times. They won't adversely affect your Power Index or Recruit Ranking. In fact, coaches would prefer to see more times so they can see your progress over time.
