High Quality Content by WIKIPEDIA articles! In the technology of the steam engine, the indicator diagram was a device developed by James Watt and his employee John Southern to improve the efficiency of engines. The diagram is simply a chart of the pressure of steam in a cylinder against the steam's volume. In 1796, Southern developed the simple, but critical, technique to generate the diagram by fixing a board so as to move with the piston, thereby tracing the "volume" axis, while a pencil, attached to a pressure gauge, moved at right angles to the piston, tracing "pressure".
