Returning to the
original spectrum
Many processing functions generate a new trace. If you have
Trace Replace mode set to Replace, the new trace replaces
the original trace. For information on Replace mode, see
Section 2.4.4, Adding Traces from the Same Data File to a
Window.
To return to the original spectrum:
• If the original spectrum was an unprocessed spectrum,
select Spectrum # from the Display menu. The number
of the original spectrum is displayed in the Select
Spectrum dialog box. Click OK.
• If the original trace was a processed spectrum, select
Processing History from the Display menu, then select
the original trace.
