Abstract
A graph display apparatus includes a plurality of functional formulas to be displayed as graphs and their coordinate ranges are stored in a memory by operating numeric .multidot. symbol keys on a key input unit. The plurality of stored formulas are displayed on a display unit by operating a 'list' key. When a plurality of arbitrary formulas are designated and a 'synthesis' key is operated, the graphs of the designated formulas are calculated and displayed on a single coordinate system in accordance with coordinate ranges of the formula which is designated first. When the plurality of arbitrary formulas are designated and a 'division' key is operated, the functional formulas are displayed on different coordinate systems in accordance with corresponding coordinate ranges. When the graphs of a plurality of input formulas are calculated and displayed, the individual graphs can be appropriately synthesized or divided and can be displayed in comparison with each other.
