Examination of age, period and cohort effects is a crucial aspect in many long-term studies. In this work, we extend a holistic APC analysis framework by introducing innovative visualization techniques facilitating the intuitive interpretation of complex temporal structures. Our concepts are motivated by the representation of age, period and cohort in Lexis diagrams. We introduce ridgeline matrices, a two-dimensional extension of ridgeline plots, to commonly visualize distributions for age groups, periods and cohorts. The established APC concept of generalized additive models is used to circumvent the identification problem by fitting a bivariate tensorproduct spline between age and period. We outline our concepts by analyzing altering travel distances of German tourists.
