Decay-time-dependent CP-violation effects in transitions of neutral B mesons to CP-eigenstates can be visualised by oscillations in the asymmetry, as a function of decay time, between decay yields from mesons tagged as initially having B or B flavour. Such images, for example for B⁰ J/ K⁰ ₒ decays where the magnitude of the oscillation is proportional to (2) with being an angle of the Cabibbo--Kobayashi--Maskawa Unitarity Triangle, provide a straightforward illustration of the underlying physics. Until now there has been no comparable method to provide visualisation for the case of decays to multibody final states that are not CP-eigenstates, where interference between CP-even and -odd amplitudes provides additional physics sensitivity. A method is proposed to weight the data so that the terms of interest can be projected out and used to obtain asymmetries that visualise the relevant effects. Application of the weighting to B⁰ₛ decays, where effects due to non-zero width difference are not negligible, provides a novel method to observe CP violation in interference between mixing and decay without tagging the production flavour.
