<p>Disclosed is chromatogram display suitable for an analyst to compare chromatograms derived from a plurality of samples with one another to accurately determine/evaluate the similarity or difference of the plurality of samples. When data files in which chromatogram data for each of the samples is stored are given, a display processing unit extracts chromatograms obtained under the same analysis condition/environment (the type of detector is the same, in the case of a UV detector, the wavelength is the same, in the case of a mass spectrometer (MS), m/z is the same, or the like), and overlaps a plurality of the chromatograms derived from the plurality of samples under the same analysis condition/environment in the same graph display frame. The display processing unit overlaps chromatograms under different analysis conditions/environments in different graph display frames, and vertically aligns and displays a plurality of the graph display frames with a time axis as the same. As a result, only meaningful chromatograms are overlapped in one graph display frame to compare the plurality of samples with one another, thus enabling the analyst to easily grasp the difference or similarity of the wavelengths of the chromatograms.</p> |
