Q: A user wants to scale the chromatogram's time axis from 10% left of reference peak 1 to 10% of reference peak 2. The name of the reference peaks is given.



  • Generate a group including a chromatogram plot   (add a dummy filed so you can generate a group around the plot)
  • Repeat the group on a suitable parameter (in order to allow filtering)
  • Filter the group on the names of the 2 reference compounds
  • Scale the time axis using min/max values of peak begin/peak end.


See the attached screenshots for further details.


By the way – you can repeat a group on the expression “=1” …

Just to get filtering.
