heal.abstract	Changing the aspect-ratio (scale) of a graphical plot significantly affects the ""messages"" getting across to a viewer. This is true also for curvature plots and other graphs currently used in Curve & Surface Modeling to evaluate fairness. In particular, the sharp corners appearing in such graphs, employed as local fairness indicators by current practices, are significantly affected by nonuniform scaling. A detailed study of this phenomenon is presented offering specific guidelines for correctly ""reading"" curvature plots.	en
