Hi Philippe,
Thanks for your answer !
It seems that with my version (2.23/12)
t->Draw("var3[][0]");
t->Draw("var3[][1]");
does not work however :
t->Draw("var3[0][]","ntrack != 0");
t->Draw("var3[1][]","ntrack != 0");
(which is quite the same)
or
t->Draw("var3[1,ntrack]","ntrack != 0");
t->Draw("var3[1,ntrack]","ntrack != 0");
seem OK ... even if in the browser I see in the last line : var3[ntrack][2]
