Designing a Good Graph.
Although computer graphics professionals usually consider only technical graphic design issues, recent improvements may make the only limiting design factors the user's purpose, imagination, style, and taste rather than computer hardware or software technology. Computer graphics designers can be helped to avoid pitfalls by understanding the visual processing functions of the brain and the way humans perceive graphs. Graphics should be designed to enhance analysis by the right brain to avoid misleading and confusing visual effects. For example, unnecessary labeling and grids and poorly chosen line weight distract the right brain's visual perception. In this case, visual impact may be enhanced by minor layout changes. Although technical problems may still affect adaptation of information to a display medium, computer graphics designers should learn to study visual effects and have a computer-based tool available to allow experimentation with such effects during the initial design stages. The points discussed in this paper are illustrated with numerous examples of different types of graph designs, and their implications are discussed. (LMM)
