PURPOSE:To easily confirm graphic structure data by calculating and displaying a part of graphic structure data less than an instructed node so as to quickly and precisely judge the sequence relation of data. CONSTITUTION:When a user issues an instruction by clicking a certain node in the graphic structure data such as knowledge data, etc., displayed on a display device B by an input device C such as a mouse, etc., and inputs a sequential display command, a sequential display position calculation means D-1 provided at a controller D finds the display position of each node in such a way that the part of the graphic structure data less than the instructed node is arranged so as not to superimpose the node and an arc as possible, and the node with the same level can be arranged on the axis on one side of a display coordinate system on a parallel straight line, and the coordinate value on the other side of the display coordinate system is prevented crossing between neighboring partial trees except for a common node, and an arranging state is displayed in a state where interval between the nodes is reduced as possible. Next, a display control means D-2 provided at the controller D performs display according to a found display position. |
