PROBLEM TO BE SOLVED: To subject graph image data prepared by a computer provided with a function calculating function, for example to an arbitrarily work, to output the data and to display them on a monitor. SOLUTION: The graph image data received from a computer 11 through a terminal 13 and a reception part 35 are stored in a received data register 36e, written in a display register 36a, displayed on a display part 16, converted to video signals by a video signal converting part 37a at a transmission part 37, outputted from a terminal 14 to a video monitor 12 and simultaneously displayed. In such a state, when a 'horizontal' key 18 or a 'vertical' key 19 and an 'area' key 20 are operated while designating any arbitrary point on the graph image data through a touch pen P, a horizontal line or vertical line and a paint-out area with a coordinate (x, y) of the designated point stored in a coordinate data register 36h as a reference, are additionally plotted, written in the display register 36a, displayed on the display part 16 while being changed, transmitted through the transmission part 37 to the video monitor 12 and simultaneously displayed while being changed. |
