[Problems to be solved] Improving learning effect. [Means to solve the problems] An alpha calculator 1 includes a memory section 13 which stores an image file 132 having image data 133, coordinate range data 138 indicating a range of an XY coordinate system set in the image thereof, and coordinate value table data 135 indicating XY coordinate values of analysis target points in the image; and a CPU 11 which makes a left side display area 3A display at least a part of an image part of the image of specified image data 133S, sets in the left side display area 3A the XY coordinate system within a range set in the image part in specified coordinate range data 138S, and makes plotted points P displayed at positions indicated by specified coordinate value table data 135S among the coordinate system. The coordinate value table data 135 correlates a coordinate value of T axis with the XY coordinate values. CPU 11 sets TX or TY coordinate system in a right side display area 3B, and makes the plotted points P displayed at positions indicated by the specified coordinate value table data 135S among the set coordinate system. |
