The Spectrum view automatically displays the spectrum linked to the active chromatogram trace and shows the first scan as the default view. As you navigate through the Chromatogram, the application updates the spectrum accordingly. The x axis displays the m/z values, the y axis displays the Relative Abundance, and the peaks are labeled with their corresponding m/z values.

You can add multiple Spectrum views to a workspace.
