<P>PROBLEM TO BE SOLVED: To display the direction of movement including a plot point, easily to watch. <P>SOLUTION: A scientific calculator 1 includes a CPU 11 which displays an image of any image data 133 in a designated image file 132S on a display screen, and a touch panel 30 which receives from a user a plot operation for a desired analysis target point in the relevant image within the display screen in the state of displaying the image of the image data 133. In response to the plot operation, the CPU 11 switches the image data 133 to be display-controlled in order within the designated image file 132S while displaying and maintaining a plot point P at a target position of the plot operation within the display screen, detects a transition direction of the plot point P within the display screen in accordance with the order of plot operations and, each time the transition direction is changed, displays each plot point P after the change in a display form different from that of the plot point P before the change. <P>COPYRIGHT: (C)2012,JPO&INPIT |
