Abstract
In a graph displaying method and apparatus and a processing operation monitoring apparatus, a succession of graph points representing the progress of a process are sequentially displayed from one side to the other on the graph display area of a screen, one added at a time to the leading end of the graph. When the latest graph point arrives at the right end of the graph display area, the graph is shifted back leftwardly to a predetermined position at a speed that can be followed by the operator's eyes, whereupon an additional succession of graph points are sequentially displayed at the leading end of the graph. While the graph is being shifted from the right end of the graph display area to the predetermined position, a plurality of transient graphs is successively displayed from the start position of the movement to the terminating position, thus maintaining continuity of the displaying graph so that the operator can monitor the progress of the process without interruption and/or misrecognition.
