These curves let you adjust the strength of curl along the length of the guides. The preset curves result in a strength of 0 at the guide roots, and a steadily increasing strength in the direction of the guide tips.

These graphs only have an effect on the curls defined by X Height and Y Height (i.e. curls along the length of the guides).
