示例1: ProjectionX
void KVCanvas::ProjectionX(TH2* hh)
{
TString pname = Form("%s_px", hh->GetName());
Int_t ip = 1;
while (gROOT->FindObject(pname.Data())) {
pname = Form("%s_px%d", hh->GetName(), ip);
ip++;
}
TH1* px = hh->ProjectionX(pname.Data());
if (!px) return;
Double_t minY = (hh->GetYaxis()->GetXmin());
Double_t maxY = (hh->GetYaxis()->GetXmax());
Double_t dY = (maxY - minY) * 0.8;
Double_t maxH = px->GetBinContent(px->GetMaximumBin());
TGraph* gg = 0;
if ((gg = (TGraph*)gROOT->FindObject(Form("%s_gjx", hh->GetName())))) gg->Delete();
gg = new TGraph;
for (int i = 0; i < px->GetNbinsX(); i++) {
gg->SetPoint(i, px->GetBinCenter(i), minY + px->GetBinContent(i)*dY / maxH);
