I am trying to make a graph that has a y-axis as "blood pressure" and x-axis as "time" (3 minutes, 6 minutes, 9 minutes, 12 min, etc.) however, I also need 4 other labels on the x-axis (systolic male, diastolic male, systolic female, diastolic females). I need the 4 labels with each time interval, so at 3 minutes I need all of those and then with 6minutes, etc. I don't know what to do. If you could help that would be great ! Thank you.
