Fig. 2. Line densities and fits for four example cities, one from each group.

Fig. 2.

(A) Decreasing. (B) Increasing. (C) CCU. (D) CCD. Line densities are shown as circles, and fits are shown as solid lines. y axis values are normalized to a range of 0 to 1, and x axis values are positioned so that the maximum value of the fit occurs at 0.
