Abstract:
1. A polygonal chart drawing processing method for drawing a polygonal chart representing relationship among evaluation values of each evaluation item for drawing objects, for which at least three evaluation items set, the method comprising: inputting evaluation items set for a drawing object and item values for the evaluation items; generating base graphics, each of the basic graphics has a vertical angle allocated based on the number of the evaluation items N at a vertex overlapped at the center point of an area where a polygon is drawn, isosceles sides, and a base to be connected to form the outline of the polygon, a centerline which is drawn from the vertex as a start point to a point bisected with the base and set as an indicator axis; generating similar figures to the base graphics, each of the graphics having the vertical angle of 2π/N and an area representing an item value of the allocated evaluation item, as item-value-corresponding graphics; and drawing a polygonal chart made of all the item-value-corresponding graphics arranged in a radial pattern by placing each of the vertexes to be overlapped at the center point of an area and by connecting adjacent bases together to form the outline of the polygon.
