Your code cannot be run, we are missing 2 data files. Also, it is much better if you reduce the code to a minimum working example that shows your problem.

Dear @dastudillo,

Thanks for your prompt response. Please see consider this version of the macro.

You have

  // gPad->SetBottomMargin(0); // Adjust bottom margin for the first pad
  // gPad->SetTopMargin(0); 
  h15->SetStats(0);          // No statistics on upper plot
  // h15->SetFillStyle(3004);
  // h15->SetFillColor(kBlue);
  // h15->GetYaxis()->SetTitle("Candidates per 0.02");//cos

  // h2 attributes
  h16->SetStats(0);          // No statistics on upper plot
  h16->GetXaxis()->SetTitle("Candidates per 0.02");//cos

When using “same”, only the axes of the first drawn histo are kept, so you should do SetTitle on h15, not h16, and similar for other pads. An alternative is to add the histos to a THStack (for each pad), so you only have to worry about formatting one object; also, note that when using “same”, if the scales, bins, limits, etc of the histos don’t match you may not see all the data of one or more of the histos, since, again, only the frame of the first one drawn is used.
