Mapping from discrete domain: length × width → discrete codomain: {A,B,Q,Q+} = stocking size. Two things. First, it’s a scale in the sense of Hadley Wickham’s ggplot: an association between logic and graphics. Second, it depicts a well-known phase space.Just like certain pressure & temperature combinations make plumbumappear as a solid, liquid, or gas [for instance the point (3180℉, 1 atmosphere)] — so do certain height & weight combinations recommend a stocking of A, B, or Q.
