<p><P>PROBLEM TO BE SOLVED: To realize a graph display control apparatus suitable for learning graph rendering by which graph features and increase/decrease table components are studied in cooperation. <P>SOLUTION: After displaying on a display unit an increase/decrease table screen W14, having an increase/decrease table W10 of a graph formula L10 being displayed, and a graph screen W12, a CPU stands by until a display unit is tapped by a pointing device. On detecting the display unit being tapped, components of the increase/decrease table W10 corresponding to the tap position are displayed for identification by means of a reverse display M12. Further, a locus of the moved tap position by the pointing device is displayed on the display unit. With a movement of the tap position from P10 to P12 through a drag operation of the pointing device, the reverse display M10 of the corresponding increase/decrease table components is changed to M12. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
