A technician is often asked to read graphs drawn by a machine. The machine records measurements by plot ting them on a graph. Any field in which quality control or continuous information is needed might use this way of recording measurements. Illustration 4 shows a microbarograph used by the weather service to record atmospheric pressure in inches. For example, the reading on Monday at 8:00 p.m. was 29.34 in.
