  • System and method for creating and modifying graphs in a computer system using a multiple segment graph format
    Patent number: 5452409
    Abstract: A system and method for creating and maintaining graphs in a computer system. The computer system contains a windowing system. The present invention performs its functions without placing a great burden on computer system resources. According to the present invention, a graph is drawn on multiple forms. The graph is initially displayed on a display screen by writing the forms to the display screen. Each form stores a single data point of the graph. A new data point is added to the graph by representing the new data point in the appropriate form. To display the new data point on the display screen, only the modified form (that is, the form containing the new data point) is written to the display screen.
