Error band in TGraph (or TGraphError)

How can I put error band for my data points in TGraph? I saw that in 1998 there was a little root discussion about error bands in TGraph, but no solution.

Hi,
use e.g. TGraphErrors::Paint(“4”); see the doc at http://root.cern.ch/root/html/TGraphErrors.html#TGraphErrors:Paint
