The measured and calculated evolution of $v_2$ (left) and $v_3$ (right) in pp and p--Pb collisions as a function of charged-particle multiplicity at midrapidity The blue and red markers represent the measured p--Pb and pp data, respectively. The calculations provided by hydrodynamical models~ are presented with colored lines. The corresponding bands mark their statistical uncertainty. For GubsHyd calculations, the statistical uncertainty is smaller than the line thickness.
