This reminds me: when I was at university doing first-year crystallography (1974), they still measured areas of peaks in X-ray diffraction graphs (which is the integral telling you the volume of each phase) by physically cutting the peak from the printed graph, and weighing it on a sensitive balance. This looks conceptually similar.
