PURPOSE:To obtain the graphic data with high quality, by making the symbol constituting the graph to be displayed, making color graph with vector display by the graphic drawing of this data, storing and displaying it to the symbol constitution data storage device. CONSTITUTION:The data to be displayed is input on the graph input operating table 2 with the graph input pen 1 and it is fed to the graph input controller 3 and stored in the symbol graph data storage device 8 via the graph processor 4. When all the symbol graph data is stored in the device 8, the color graph by the vector display corresponding to the graph data is output at the graph drawing device 7 with the graph drawing controller 5, and it is stored in the graph data storage device 9. Next, the device 4 decomposes the symbol into video element and stores in into the video element data storage device 10 and symbol constituting data storage device 11, and the data in the device 11 is read out to the device 4, the CRT display data is formed based on the graph drawing data, and it is stored in the CRT storage device for display. |
