Fig. 3: Chronotype influence on light exposure timing.
From: Physiologically-relevant light exposure and light behaviour in Switzerland and Malaysia

Dependency of the mean timing of light above 250 lx melanopic EDI (MLiT250) against chronotype (mid-sleep) for each site. Dots indicate value pairs, the line and bands a linear model of the dependency. Correlation values (r-values) at the top of each panel show the (circular) correlation coefficient of the dependency, including its p-value.
