  Davis-Yin splitting (DYS) has found a wide range of applications in
optimization, but its linear rates of convergence have not been studied
extensively. The scaled relative graph (SRG) simplifies the convergence
analysis of operator splitting methods by mapping the action of the operator
onto the complex plane, but the prior SRG theory did not fully apply to the DYS
operator. In this work, we formalize an SRG theory for the DYS operator and use
it to obtain tighter contraction factors.
