Abstract
A graphic drawing method and system are provided to display a composite graphic composed of a plurality of fundamental graphics wherein an operator designates at least two points on a display screen using a pointing device to automatically display a straight line or a curve coupling the two points. As the coordinates input mode, there are provided an ordinary input mode and an auto-adjust mode. If a coordinate input command is given in the auto-adjust mode, it is determined whether the coordinates already inputted are present within a small area spaced apart by a predetermined distance from the cursor position. If present in the small, predetermined area, the coordinates already inputted are used as the present input coordinates. If not present in the small, predetermined area, the position coordinates of the cursor are used as the input coordinates.
