Sumario:A multi-dimensional analysis of charmonia in pp, pPb, and PbPb collisions with the CMS detector will be presented. The prompt $\ensuremath{J\hspace{-.08em}/\hspace{-.14em}\psi}$ ~nuclear modification factor and azimuthal anisotropy in PbPb collisions will be presented. In addition, the suppression pattern of prompt $\ensuremath{\psi(2S)}$ ~and $\ensuremath{J\hspace{-.08em}/\hspace{-.14em}\psi}$ ~in pp and PbPb collisions will be compared. The pPb differential cross-sections of prompt $\ensuremath{J\hspace{-.08em}/\hspace{-.14em}\psi}$ ~will be shown in a wide kinematic region, for transverse momentum spanning from 2 to 30 GeV/c and a rapidity interval between -2.87 to 1.93 in the center of mass frame. The ratio of yields in forward (p-going) and backward (Pb-going) directions is measured to quantify the asymmetry of cross-sections as a function of pT, rapidity, and event activity.
