Relative $\Dzero$, $\Dplus$ and $\Dstar$ meson yields for two selected $\pt$ intervals as a function of charged-particle multiplicity at central rapidity The relative yields are presented in the top panels with their statistical (vertical bars) and systematic (empty boxes) uncertainties, apart from the feed-down fraction uncertainty, which is drawn separately in the bottom panels The position of the points on the abscissa is the average value of $(\dNdEta) \big/ \langle \dNdEta \rangle$ For $\Dplus$ and $\Dstar$ mesons the points are shifted horizontally by $1.5\%$ to improve the visibility The diagonal (dashed) line is also shown to guide the eye
