A graph display device is capable effectively confirming data of painting points on a scatter diagram when the scatter diagram is integrally displayed. A pointer is moved to a desirable painting point P(n), clicking the mouse to mark focused data (white dots) for displaying. The mark of the focused data moves to the rear direction (forward direction) on a time axis and stops at a painting point P(n+1) at the nearest moment when a forward button (BT1) is clicked. The mark of the focused data moves to the front direction (returning direction) on a time axis and stops at a painting point P(n-1) at the nearest moment when a back button (BT2) is clicked. Data values (X,Y) of the stopped painting points and the time are displayed on a data display portion. The mark of the focused data automatically stops at adjacent painting points on the time axis. |
