Abstract:
1. An extended portfolio chart drawing device drawing a chart incorporating radar chart information of an evaluation object on a portfolio chart, comprising: a portfolio drawing unit drawing the evaluation object on the portfolio chart; a radar chart data storage unit storing radar chart data indicating each evaluation value of predetermined evaluation items for the evaluation object drawn on the portfolio chart; a drawing object selection unit selecting the evaluation object from the evaluation objects drawn on the portfolio chart to display the radar chart data; and a graphic drawing unit overlaying a predetermined graphic generated based on the radar chart data of the selected evaluation object on the graphic of the selected evaluation object drawn in the area formed with the coordinates of the portfolio chart, wherein the graphic drawing unit draws, as the graphic, a polygon representing the relationship between all the evaluation values of the selected evaluation object to be drawn on the radar chart, an evaluation item designation unit designating one of the evaluation items to be displayed on the portfolio chart, wherein the graphic drawing unit obtains the evaluation items set for the radar chart, set each index axis of the evaluation items to a line, a direction of which is predetermined as the index axis specified by a rotation angle from the predetermined base line, sets the starting position on the index axes, which is the vertex of the rotation angle, at the position of the evaluation object in the coordinates of the portfolio chart, determines points representing the evaluation values on the index axes individually, and draws a polygonal graphic containing all the determined points as apexes representing the designated evaluation item by a direction of a bisector of the apex angle and the value of the evaluation item by a length of the bisector from the starting point to the apex.
