ABSTRACT:
A digital plotting system for displaying straight line information. This tem employs a long vector to describe a long straight line on a graph that starts from any point, extends in any direction and has a specific length. The direction is implemented by an eight 45.degree. quadrant system wherein the specific angle within a particular quadrant is derived from binary slope storage and rate generator devices and is referenced from either a vertical adjacent line or a horizontal adjacent line. The long vector logic is compatible for use with a digital plotting system for displaying all forms of graphic information including curved lines, straight lines and characters.
