Notes: The chart shows a sequence of skin temperature changes over time. The 'Normal Day' line serves as a baseline, with 'Highest' and 'Lowest' offset lines plotted at +16°F and -11°F respectively. Intermediate offset lines are partially visible in some segments and are identified by the '(Offset Sequence' labels (1 through (8 in the middle of the plot.)))
