An example method for displaying longitudinal data includes receiving longitudinal data comprising a plurality of measurements of a variable occurring over a period of time and identifying a first point of interest and a second point of interest in the longitudinal data. The example method includes displaying, in a graph, the first point of interest and the second point of interest in a first time scale. The example method also includes displaying, in the graph, a portion of the longitudinal data occurring between the first point of interest and the second point of interest in a second time scale, which is different than the first time scale.
