Hi, (excuse me for my english)
I created a tree with some variables, someone can tell me how do for to
have an plot with my desidered bin when click on the leaf of the
tree?
 {...
  TTree *tmc = new TTree("tmc","Tree for montecarlo");

  tmc->Branch("dalix_mc"    ,&dalix_mc    ,"dalix_mc/D"    );
  tmc->Branch("dalix_mc_rec",&dalix_mc_rec,"dalix_mc_rec/D");
  tmc->Branch("daliy_mc"    ,&daliy_mc    ,"daliy_mc/D"    );
  tmc->Branch("daliy_mc_rec",&daliy_mc_rec,"daliy_mc_rec/D");
  tmc->Branch("daliy_ch_rec",&daliy_ch_rec,"daliy_ch_rec/D");
  tmc->Branch("isrec"       ,&isrec       ,"isrec/B"       );
  ...
  tmc->Fill();
