Bollettino dell'Osservatorio della Regia Università di Torino, 1885 (vol. 20)
This is a meteorological chart section from the 1885 Bulletin of the Royal University of Turin Observatory, produced by the Turin astronomical observatory for scientific readers. The two pictures show May 1885 daily charts with stacked traces for barometric pressure, temperature, vapour tension and relative humidity, plotted on gridded graph paper with Italian labels. A designer could take the crisp, rule-based grid layout and the rhythmic wave lines as a clean template for data graphics or dashboard headers.
