In the three-dimensional space plane fisheye magnifying display method of the present embodiment, a plurality of overlapping figures are moved at a desired ratio from the reference position so that the distance between the figures is increased. The idea is to eliminate the overlapping of figures.

In FIG. 1, one figure 1 out of a plurality of figures displayed in this manner on the display device is displayed, but the term "figure 1" is referred to as each figure 1 according to the description. As a representative. In the present embodiment, each graphic 1 is moved by a desired distance so as to eliminate the overlap between the graphics. However, the moving distance depends on the distance of each graphic from the reference position. Since it is calculated by the desired parameter, the distance between each figure is also expanded according to this movement distance,
The overlapping of each figure will be eliminated.

In the present embodiment, as shown in FIG. 1, a straight line 3 is first designated on the display screen on which the graphic 1 is displayed. Various methods are conceivable for designating the straight line 3. For example, the user observes the display screen and designates a straight line representing the tendency of arranging the linearly connected figures at, for example, two points on the display screen. A method of connecting these two points to form the straight line 3 may be considered.

Next, the designated plane 7 passing through the designated straight line 3 and the user's viewpoint 5 as described above is calculated. then,
In order to eliminate overlapping of figures, an enlarged display application range, specifically, an enlarged display application range end 9, which is a range of the enlarged display, is designated by an appropriate means. As this means, for example, there is a method of designating a plane parallel to the designated plane 7 by inputting a distance r2 from the designated plane 7.

Next, the coordinates (x, y, z) of each figure 1 are obtained. Then, the distance r1 between each figure 1 and the designated plane 7 is calculated. Next, the coordinates P1 (x1, y1, z1) of the foot of the perpendicular line between each figure 1 and the designated plane 7 are obtained.

Next, the parameter d for designating the degree of expansion is input, and using this parameter d, the expansion movement distance r of each figure 1 shown in FIG. 2 is calculated by the following equation.

[0021]

## EQU1 ## r = {(d + 1) * r1 * r2} / (d * r1 + r2) Then, in order to move each figure 1 to the expanded moving distance r calculated in this way, as shown in FIG. And the coordinates (x0, y0, z0 of each figure 1 at the position to be moved.
) Is calculated by the following equation, and each figure 1 is rearranged at this coordinate position.

## EQU2 ## Coordinates (x0, y0, z0) = (x1 + r * (x
-X1) / r1, y1 + r * (y-y1) / r1, z1
+ R * (z-z1) / r1) As described above, in the present embodiment, as a result of displaying information in the three-dimensional space as a group of figures, the straight line 3 is removed in order to eliminate the overlap in these figures. The display is designated and displayed, and further the enlarged display applicable range end 9 is displayed, and the user directly designates the parametric variable d relating to the moving distance of the figure in the direction orthogonal to the designated plane 7 passing through the straight line 3 and the user's viewpoint 5. By doing so, the graphics are moved, the display results are immediately redisplayed, and the graphics are arranged in a straight line. Overlap can be eliminated while holding. By eliminating the overlap of the plurality of figures in this way, each of the plurality of figures can be displayed accurately, and the efficiency of supporting the understanding of the data analysis result can be improved.
