Unable to Retain the Style of the projection Histogram on using HBAR

Hi,

I mean to create TGraph from histogram points like this:

TGraph *make_swapped_graph(TH1 *h1) {
   // copy all points from histogram
   TGraph *gr = new TGraph(h1);
   Int_t nbins = gr->GetN();
   Double_t x,y;
   // swap x/y coordinates
   for (int n=0;n<nbins;++n) {
      gr->GetPoint(n,x,y);
      gr->SetPoint(n,y,x);
   }
   return gr;
}

And then draw such graphs instead of histograms.
Here is complete macro - with few errors corrections: b2_style_pad.C (7.4 KB)

And produced image.
