I showed a May Institute participant how to use View > Transitions > Split Graph to view all the transition chromatograms for multiple precursor charges of a peptide, but as I was looking at the resulting graph I realized there was no easy way to tell what the precursor charge was for which graph pane without expanding the peptide an matching positionally. Was it + and ++ or ++ and +++ or +++ and ++++ or some other combination. The legend only contained the fragment ions and most of those were singly charged in both cases. In other case, the legends for the chromatograms usually help, like precursors versus fragments or even light versus heavy.

I am not sure exactly where to show this information in the plot, but it sure was confusing without it.
