draw and save many leafs of a brance

hi,
  I now begin use TTree,the script is like this:

           TFile fr("spt.root","new");
           TTree *spt=new TTree("spt","spt check");
           spt->Branch("time",&timee,"time/D");
           spt->Branch("count",grbEvent.r,"count[8][80]/I");


            ......

           spt->Fill();


            ......

            fr.Write();
            fr.Close();
          After open the spt.root file,I can draw figures one by one with the
command:spt->Draw("count[0][0]:time");
        spt->Draw("count[0][1]:time"); 
        spt->Draw("count[0][2]:time");
         ............................  
        but 640(8*80) figures will cost much too time.
        I want to know if there are methods to draw these figures and save
quickly?
                  
       Thanks a lot  
      

with best wishes,
