Currently when you show a QC (pressure etc) trace it supersedes the display of transition chromatograms. There is a user request to show it overlaid, no need for a second set of units.

There is also an unrelated Wishlist:
"-Have a maximum pressure replicate comparison to monitor health of column.
-Being able of overlay pressure traces between different samples on the same plot (just for publication purposes). This would actually be nice not only for the pressure plots, but also for the intensity signals for the targets (other programs allow you to slightly offset X (intensity) and Y (time) among different samples to illustrate 'biological differences'. I realize this would probably be another separate request."
