PURPOSE:To display an interval between two points continuously and in an uniform line segment by providing a state holding means, a display control means, and a state decision means having prescribed functions respectively. CONSTITUTION:A state holding means 1 holds a partial line segment Li, a residual length (l) in which a displayed part is excluded from the line segment Li, and a residual length (d) in which the displayed part has been excluded from a whole length to be displayed. A display control means 2 controls a display state based on a length relation between lengths (d) and (l), and whether (i) in the Li is an even or an odd. A state decision means 3 decides the next state according to a regulation regulated in advance, and displays it repeatedly. In this way, the interval between continual two points can be displayed in a short dashed line, a chain line with one dot, or the chain line with two dots continuously and uniformly. |
