The command "Highlight all assigned Functional Groups" provides
a quick way of visualizing all vibrations in the current spectrum that
are already assigned to functional groups in the interpretation result.
This enables the user to quickly reveal all assigned and yet unassigned
vibrations for further optimization or additional manual interpretation.
The selection of this command toggles highlighting on or off. All identified
functional groups are colored blue as shown in the following figure:
The transparency level of blue colored vibrations indicate, which bands
belong to the current selected functional group. Vibrations of the current
selected functional group are marked dark blue. Others are light blue.
On selection of a different functional group, colors of the current selected
group return to original coloring and others keep their blue shape.
