Evolution with the average charged particle multiplicity of the longitudinal (left) and azimuthal (right) widths of the two-particle transverse momentum differential correlation $G_{2}^{\rm CD}$ (top row) and $G_{2}^{\rm CI}$ (bottom row) in pp, p--Pb, and Pb--Pb collisions at $\sqrt{s} = 7\;\text{TeV}$, $\sqrt{s_{\rm NN}} = 5.02\;\text{TeV}$, and $\sqrt{s_{\rm NN}} = 2.76\;\text{TeV}$, respectively. Vertical bars (mostly smaller than the marker size) and filled boxes represent statistical and systematic uncertainties, respectively.
