[ROOT] TTree::Draw question

   Hello Rooters.

    I have a TTree with a branch that contains an array.  I would like to
plot the values of the array vs. the index.

 for example, I have

   Float_t time;
   Float_t loss[10];
   

   TTree* foo=new TTree("foo","On You");
   foo->Branch("time",&time,"time/F");
   foo->Branch("loss",&loss,"loss[10]/F");	

   //fill the tree

   In a perfect world I'd like to do
   foo->Draw("loss:i");
   and
   foo->Draw("loss:i:time");

  Can you help.  I am using ROOT cvs from Monday.
