To provide a method for simulating, plotting, and verifying the creation of a graphic by a creating means for deciding the various origins of a graphic so that a plurality of adjacent graphics expressed with closed curves can be provided with complementation.

A segment with predetermined length "L" having one end on a revolving orbit with a predetermined radius "r" from a graphic center (S) is rotated with one end on the orbit as the center of rotation, and revolved at the angle of rotation which is three times as large to a direction opposite to the rotating direction, and revolved three times so that a graphic expressed with a closed curve constituted of an orbit plotted by the other edge of the segment can be obtained as a first graph (H1). Then, an orbital circle radius "r1" and a rate "η1" of the radius "r1" and the segment length "L1" are decided, and an inter-center distance "s" of adjacent graphics (H1, H2) is calculated. Then, an orbital circle radius "r2" of the second graphic (H2) having complementation with the first graphic (H1) and a rate"η2" of the radius "r2" and segment length "L2" are calculated. The first and second graphics (H1, H2) are plotted on one picture plane, and the complementation of those graphics is decided from the plotted picture plane so that the various origins of the graphics can be decided.
