Hi Rene,

   thanks for the bits, now the visualization, zooming and unzooming is working. However now i've problem in other fields: 1) i'm not able to use correctly the FitPanel since it performs the fit in a location different to that selected with the bar in the panel;
2) I'm not able to save the TGraph in a root file, since when i reopen the saved root file and plot the graph, nothing appears. This is the code i've added to the past macro:

  TFile *dati = new TFile("dati.root","RECREATE");    gr->Write("Cm245");


Many thanks,
