Extended portfolio chart drawing device, processing method and computer-readable medium recording a program of the same

摘要

An extended portfolio chart drawing device draws an evaluation object on a portfolio chart. The chart drawing device selects the evaluation object to draw a radar chart, extracts a score from an index axis of an evaluation item designated by a dial drag position detection unit for the selected evaluation object from the radar chart data, and draws a triangle representing the direction of the index axis and the score of the evaluation item at a position of the corresponding evaluation object on the portfolio chart. Then, the chart drawing device draws a polygon representing the relationship between all the evaluation values for the selected evaluation object to be expanded from the radar chart data at the position of the corresponding evaluation object on the portfolio chart.
