That is, a plurality of spectral data display curves may be displayed using lines of different types (for example, lines of different colors in a color CRT display device, lines of different line types such as solid lines or dotted lines in a monochrome CRT display device, etc.). A straight line cursor for indicating a selected spectral data display curve on a CRT display device that is configured to be able to simultaneously display lines (lines of different thicknesses, lines of different brightness, etc.) on a graphic display screen. is displayed on the graphic display screen, in the method of the present invention, a straight line cursor consisting of a line of the same type (color, line type, thickness, brightness, etc.) as the selected spectral data display curve is displayed. Therefore, even if there are a large number of spectral data display curves displayed within the graphic display screen, or even if each spectral data display curve is close to each other, other information such as special textual information You can determine the correspondence between the selected spectral data display curve and the straight line cursor that indicates it by simply visually observing the vicinity of the intersection of the straight line cursor and the spectrum data display curve consisting of the same type of line as the straight line cursor, without having to rely on it. Of course, it is also possible to easily and reliably identify at a glance, that is, intuitively, which part of the selected spectral data display curve the straight line cursor is pointing to.
