The graph is aiming for the representation of Figure 2 in Kjaergaard et al 2013. (http://dx.doi.org/10.1021/bi4001062).
The figure can be seen at https://gna.org/support/download.php?file_id=20208.
It becomes clear, that it is not neccessary interpolate through the spin-lock offset, but it is suffucient to interpolate through the spin-lock field strengths.
The necessary step was the extraction of the effective effective field in rotating frame, w_eff.
In earlier attempt is shown at:

This though show lines for 6 offset values.
The question is how to show the single line of interpolation.
sr #3124(https://gna.org/support/?3124): Grace graphs production for R1rho analysis with R2_eff as function of Omega_eff.
sr #3138(https://gna.org/support/?3138): Interpolating theta through spin-lock offset [Omega], rather than spin-lock field strength [w1].
