PURPOSE:To display data editting them in a scale so as to easily recognize the fluctuation of values by displaying the data exceeding a rate set by a user as a void graph. CONSTITUTION:At a graph preparing device 3, a graph data input means 4 possesses data for graph output from an input device 1, a graph image generating means 5 prepares a graph image and a graph output means 6 outputs the graph image to an output device 2. At a central blanking symbol control device 7, a control part 8 controls the flow of the graph output. A data transforming means 9 transforms the data into the void data as needed and holds the data in an internal storage device 10. A central blanking symbol adding means 11 adds a void symbol to the void data in the internal storage device 10. |
