PHASEPLOT: An On-Line Graphical Display Technique

A parametric display technique for on-line graphical output is presented. This technique is particularly useful for rapid display of continuous ``smooth´´ data, through relatively few computer commands. Graphical data to be displayed are composed from primitive segments, each of which corresponds to one computer command that specifies starting and stopping point, final slope, and ``curvature.´´ Presented topics include the basic principle of operation, a class of hardware realizations, typical software requirements, and experimental results of a display prototype.
