Ah ok, so definitely not mg/L that is fine.
The values are definitely for the x-axis, I've discovered that I have to infer the Y values from the quantity of x values within same positions to gauge the relative intensity of the chemicals ions/molecules.
Ergo the Y axis is 'relative intensity' or 'signal intensity of area', would you agree with this?
I can't divulge much about the project unfortunately however I can say that it is not simply the visualisation of NMR Spectra. :-)
Thank you again,
