PURPOSE:To flexibly deal with individual graphs by properly putting them together or dividing them when plural input expressions are displayed as graphs. CONSTITUTION:While plural function expressions to be displayed as graphs and their coordinate ranges are stored by operating numeric and symbol keys 14 of a key input part 11, the expressions are all displayed at a display part 12 by operating a 'list' key 16; when plural optional expressions are specified and a 'composition' key 17 is operated, the respective specified expressions are put together and displayed as a graph according to the coordinate rate of a 1st specified expression, and then plural optional expressions are specified and a 'division' key 18 is operated. Consequently, the graphs are divided and displayed individually according to the corresponding coordinate ranges and when the 'composition' key 17 is operated in the divided display state, one graph and the other graph are put together and displayed on the same coordinates with an 'EXE' key 20; when a 'copy' key 19 is operated, one graph is copied onto the other graph and displayed with the 'EXE' key 20. |
