Only one spectrum can be displayed in a pane. Stacking spectra is useful when
you are comparing spectra that are significantly different. For example, stacking
the library spectra found in a spectral search can make it easier to decide which
spectrum most closely matches the unknown sample.
When you stack spectra, you set the number of panes in the spectral window by
using Display Setup in the View menu (see “Specifying how to stack spectra” in
the “View” chapter for details). There can be more panes in the window than there
are spectra, resulting in one or more empty panes. There can also be more spectra
in the window than there are panes. In this case some spectra may be out of view
“above” or “below” the panes. You can scroll spectra into view or into an empty
pane (this is explained below).
Each pane in the stack has its own Y-axis. Any X-axis adjustments that you make
using the view finder will affect all of the spectra in the window.
Displaying a list of stacked spectra – Click the arrow at the right end of the
title box to see a list of all the spectra in the window, including those out of view.
The spectrum titles appear in the list in order from top to bottom.
Hiding a stacked spectrum – Use Hide Spectra in the View menu to hide a
stacked spectrum so that it doesn’t appear on the screen (see “Hiding spectra” in the
“View” chapter for details). When a stacked spectrum is hidden, its title appears in
the font specified for the titles of hidden spectra in the View options. The default
font for displaying the titles of hidden spectra is italic. (See “Specifying fonts for
displayed text” in the “Edit” chapter.) In the example below, the spectrum titled
“Aromatic Compound” is hidden.
