<P>PROBLEM TO BE SOLVED: To provide a spectrum display device capable of effectively displaying a spectrum. <P>SOLUTION: A spectrum display device 100 makes a first axis have predetermined physical quantity, and expands and displays a part of a spectrum which indicates that a second axis has strength to the predetermined physical quantity. The spectrum display device includes: an operating portion 10 for designating an expansion range of the first axis of the spectrum; a range information obtaining portion 22 for obtaining information on the expansion range designated by the operating portion 10; a spectrum producing portion 24 for producing an expansion spectrum in which the expansion range is expanded along the first axis at a predetermined expansion rate, and a range of the first axis different from the expansion range is contracted along the first axis at a predetermined contraction rate, on the basis of the information on the expansion range; and a display portion 30 for displaying the expansion spectrum produced by the spectrum producing portion 24. <P>COPYRIGHT: (C)2013,JPO&INPIT |
