Feature request: export ΔRFU linear bars grouped by state

[Jhsmit]

Feature request (web application): Select one state as reference, then export linear bars grouped by state, consisting of the various exposure times

The problem with this at the moment is the unfortunate plotting API where the plotting functions take a reference parameter and then calculate dRFU / dG if this is given. It would be better to input the dRFU / dG data directly
