Match the Y-axis scale of a spectrum
1. Select the spectrum.
2. Choose Match Scale from the View menu.
All the spectra in the window are displayed using the Y-axis limits of the
selected spectrum, and a check mark appears next to the command name. If
you change the Y-axis limits of the spectra, the check mark is removed.

Match Scale is useful for comparing the relative intensity of bands using one
spectrum to set the scale for all.
If you add a spectrum to the spectral window after using Match Scale, the
added spectrum will also be displayed using the matched scale.
Displaying spectra
vertically offset
If you are overlaying spectra, you can use Offset Scale in the View menu to
display the spectra in the active spectral window vertically offset from each other.
Separating the spectra in this way lets you compare their spectral features at any
frequency.
The following example shows three overlaid spectra.
