Synchronize

The synchronization action can be applied/removed from the Syncronize button in Mass/Tools, or via context menu from chromatogram or mass spectrum plots. 

On enabling synchronization, all the chromatograms are synchronized to the X axis range of the current active chromatogram. Any modification in X axis of a chromatogram (zoom or panning) will be reproduced in the other chromatograms.

Appending new chromatograms or MS spectra to the spectral window also applies the current synchronization state.
