Abstract: A display system comprising a display and a memory for storing a plurality of evaluation data relating to a plurality of types of clothing and accessories. Each type of clothing and accessory has a respective plurality of colors. The display is controlled to display the plurality of types of clothing, a plurality of types of accessories to be carried, and the respective plurality of colors of each of the types of clothing and accessories. A designating device is provided for designating particular combinations of clothing and/or accessories. When a first article of clothing of a designated color is combined with a second article of clothing and its designated color, an evaluation of this combination is performed based on the stored plurality of evaluation data, and the resulting evaluation is displayed on the display.

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.
