1. A spectral flow cytometer apparatus comprising:
a light source, in the spectral flow cytometer apparatus, configured to irradiate light with a first wavelength region to a plurality of particles, wherein the particles include cells flowing through a flow path in the spectral flow cytometer apparatus stained with at least one of a plurality of fluorescent dyes;
an optical filter, in the spectral flow cytometer apparatus, that filters lights generated from the plurality of particles to limit the lights within the first wavelength region;
a plurality of detectors, in the spectral flow cytometer apparatus, configured to detect lights filtered by the optical filter, each one of the plurality of detectors respectively corresponding to each one of a plurality of wavelength regions; and
a processor, in the spectral flow cytometer apparatus, configured to output analysis data for displaying a spectrum chart corresponding to each intensity value of the detected light in each one of the plurality of wavelength regions,
wherein a number of the fluorescent dyes which are stained on the cells flowing through the flow path in the spectral flow cytometer apparatus is less than a number of the detectors in the spectral flow cytometer apparatus.
