Dynamical net-charge fluctuations, $\nu_{(+-,dyn)}$ and their corrected values,$\nu^{corr}_{(+-,dyn)}$, for charged particles produced in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=2.76$ TeV as a function of centrality, expressed as the number of participating nucleons. $\nu^{corr}_{(+-,dyn)}$, points are shifted along $x$-axis for better representation. Superimposed are the results for pp collisions at $\sqrt{s}=2.76$ TeV. The statistical (bar) and systematic (box) errors are plotted.
