As explained in the last paragrah of http://root.cern.ch/root/HowtoConvert.html The notation Draw("JetPt[1]") is not supported in version 0.9. This will be part of version 1.0 Currently, you have to loop yourself on your events. Note that a skeleton function can be automatically generated. This is explained in the URL above. Rene Brun
