Top: Normalized yield of inclusive $\Jpsi$ as a function of the normalized charged-particle pseudorapidity density, measured at midrapidity, in various collision systems. Bottom: Ratio of the normalized yields to the corresponding normalized charged-particle pseudorapidity density. The pp results are normalized to INEL collisions , whereas \pPb ones refer to the NSD event class; all for $\pt>0$. The Pb--Pb data points include $\Jpsi$ with $0.3
