  Charmonium-like resonances and bound states with isospin zero and
$J^{PC}=0^{++},~1^{--},~2^{++},~3^{--}$ are extracted on the lattice. Coupled
$D\bar D$ and $D_s\bar D_s$ scattering suggests three charmonium-like states
with $J^{PC}=0^{++}$ in addition to $\chi_{c0}(1P)$: a so far unobserved $D\bar
D$ bound state just below threshold, a conventional resonance likely related to
$\chi_{c0}(3860)/\chi_{c0}(2P)$ and a narrow resonance just below the $D_s\bar
D_s$ threshold with a large coupling to $D_s\bar D_s$ likely related to
$X(3915)/\chi_{c0}(3930)$. One-channel $D\bar D$ scattering renders resonances
and bound states with $J^{PC}= 1^{--},~2^{++},~3^{--}$ related to the observed
conventional charmonia. Lattice QCD ensembles from the CLS consortium with
$m_{\pi}\simeq 280$ MeV are utilized.
