Constructor & Destructor Documentation

HistDisp::HistDisp (  UgliGeomHandle  ugh, TPad *  pad = 0 )

Create a HistDisp. An UgliGeomHandle is needed to find the extents. If no TPad is given a newly created TCanvas is used. Definition at line 14 of file HistDisp.cxx. References fHquz, fHqvz, fPad, DataUtil::GetDetectorBinsUV(), DataUtil::GetDetectorBinsZ(), and Init(). { int nzbins=0, nwbins=0; double zmin=0,zmax=0,wmin=0,wmax=0; GetDetectorBinsZ(ugh,nzbins,zmin,zmax); cerr << nzbins << " " << zmin << " " << zmax << endl; GetDetectorBinsUV(ugh,PlaneView::kU,nwbins,wmin,wmax); cerr << nwbins << " " << wmin << " " << wmax << endl; fHquz[0] = new TH2D("quz","Charge/strip in U vs. Z", nzbins,zmin,zmax,nwbins,wmin,wmax); GetDetectorBinsUV(ugh,PlaneView::kV,nwbins,wmin,wmax); cerr << nwbins << " " << wmin << " " << wmax << endl; fHqvz[0] = new TH2D("qvz","Charge/strip in V vs. Z", nzbins,zmin,zmax,nwbins,wmin,wmax); if (pad) fPad = pad; else fPad = new TCanvas("hdc","HistDisp Canvas",800,800); this->Init(); }
