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.
A:
- 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.
