From: Tracking of voluntary exercise behaviour over the lifespan
Tracking coefficient heatmap of total volume of exercise. The inset in the bottom right corner represents sample size (N) in each cell, cut off at N = 300 for visual purposes. Colours in the main panel represent the value of the tracking coefficient (grey to blue to red from low to high), colours in the inset represent number of samples (grey to yellow to red from low to high). To demonstrate; the cell in the full circle represents the tracking coefficient (0.81) of age 48 at baseline, and age 62 at follow-up in females. The cell in the striped circle represents the tracking coefficient (0.57) of age 22 at baseline, and age 26 at follow-up in males
