2) The “Set Differential Chromatogram” dialog box appears.

3) From the combo box, select graph names for which to determine difference.
Chromatograms currently registered in pens 1 to 8 are displayed in the combo box
(differential chromatograms are excluded).
Chromatograms shown in selective graph 1 are those to be used as reference, and
chromatograms shown in selective graph 2 are to be used to compare differences with the
reference.
4) Click the OK button.
5) The obtained differential chromatogram name is displayed in the appropriate combo box of
the Set Pen dialog box. The display format is “n-m”, where “n” represents the pen number
of chromatogram selected in selective graph 1, and “m” represents the pen number of
chromatogram selected in selective graph 2.
4.4.17 Displaying Chromatogram File by Drag & Drop
1) When you have dragged and dropped a chromatogram file on to a chromatogram, the file
chromatogram is displayed. The pen displayed at this time is the one that has the smallest
pin number among unused ones. Temperature data and pressure data are not displayed
automatically.
2) If chromatograms of multiple detectors are stored in a single file, unused pens are
automatically assigned to the detectors in ascending order of detector number.
3) From the combo box in the Set Pen (file chromatogram) dialog box, you can select a
graph name currently displayed and a chromatogram name for each detector stored in the
dragged-and-dropped file. From this dialog box, select a chromatogram for overwriting.
