Significance to technology: ``With deflection measuring element which drives a recording pen or stylus across a moving paper chart a distance proportional to the quantity being measured. The moving chart is driven by a motor-driven mechanism at a speed proportional to time at a desired rate. Thus a curve or graph results which shows the variation of quantity measured with respect to elapsed time.`` (Elec. Metermen’s Handbook, p. 271)
