Bar graph representations of process variables are compared with alternatives (stroke-type and ‘T’-type, combined bar and stroke) in experiments with human subjects, using either an automatic slide projector or a closed-circuit TV system. The stroke-type appears to give superior results when used for detection of off-normal conditions.
