We consider some self-affine fractal functions previously studied by Barnsley
et al. The graphs of these functions are invariant under certain affine scalings, and we extend their definition to allow the use of nonlinear scalings. The Hölder exponent, h, for these fractal functions is calculated and we show that there is a larger Hölder exponent, h
λ, defined at almost every point (with respect to Lebesgue measure). For a class of such functions defined using linear affinities these exponents are related to the box dimension D
B of the graph by h≤2− D
