The presence of labels should not cause excessive clutter or detract from detailed information.
Additional Information:
Because labels may be large and may require large separations (Guideline 1.3.3-6), they tend to clutter large displays. The EPRI URD requirements for the MCR Integrating Display and Mimic state, "Labels which are to be read at a distance shall be minimized; however, when the display is viewed from close range, each display quantity should be specifically identified by a label readable at the short distance." The need for labels may be reduced if graphical means such as mimics and symbols are used to identify information.
