发明名称 Electronic graph drawing apparatus
摘要 An electronic graph drawing apparatus comprises an input device for inputting numerical data, a memory responsive to the input device for storing the input data, a selection circuit responsive to the memory for selecting the maximum numerical data from the input numerical data, and a define circuit responsive to the selection circuit for defining an integer as the maximum of the scale in a graph to be drawn. Additionally, a second define circuit may be provided for defining the number of sectional divisions between the maximum scale and the minimum scale. Further, a scale assignment circuit may be provided for assigning scale information. Still further a line drawing circuit may be provided for drawing broken lines parallel to the X- and the Y-axis.
