Inequality display device and inequality display program

摘要

PROBLEM TO BE SOLVED: To distinguishably color-display overlap parts where a plurality of areas overlap without requiring high specification hardware.;SOLUTION: A scientific electronic calculator 1 includes a display part 14 and a CPU 11 which displays a graphic in the display part 14 and makes first to fifth identification colors c1 to c5 associated with a plurality of inequality areas included in the graphic. The CPU 11 displays, in the display part 14, overlap parts A1 to A3 where the number of inequality areas overlapping is smaller than 5, in patterns using mixture of the first to fourth identification colors c1 to c4 corresponding to respective inequality areas overlapping in the overlap parts A1 to A3, and displays an overlap part A4 where the number of inequality areas overlapping is 5 or larger, in the display part 14 in a pattern using black and white.;COPYRIGHT: (C)2011,JPO&INPIT
