29//
30// Initialization
31// --------------
32//
33// MHn is a histogram class which derives from MH as all Mars histogram
34// classes do, i.e. to fill the histogram use MFillH. (Example below)
35//
36// After instantisation of MHn add the histograms of your interest using
37// AddHist. Before the next AddHist is called you can now set the options
38// of your histogram using InitName, InitTitle, SetLog, SetAutoRange,
39// SetScale and SetDrawOption.
40//
41//
42// Layout
43// ------
44//
45// The layout of the histograms on the screen depends on the number of
46// initialized histograms and the option SetLayout. For details see below.
47//
48// SetLayout(MHn::kSimple)
49// < default > SetLayout(MHn::kComplex)

104//
105// // Initialize your first histogram (here a 2D histogram with x- and y-axis)
106// hres.AddHist("MMcEvt.fEnergy", "log10(MEnergyEst.fVal)-log10(MMcEvt.fEnergy)");
107// // Initialize the name of the histogram (ResEmc) and the title of the
108// // binnings ((here BinningEnergy for x-axis and BinningEnergyResidual for y-axis)
109// hres.InitName("ResEmc;Energy;EnergyResidual");
110// // Initialize the title of the histogram and the axis titles
111// hres.InitTitle(";E_{mc} [GeV];\\Delta lg E;");
112// // Initialize the draw option for the histogram
113// hres.SetDrawOption("colz profx");
114// // for more details on the options and more options see below
115// // or the class reference of MH3
116//
117// // Initialize a second histogram
118// hres.AddHist("MPointingPos.fZd", "log10(MEnergyEst.fVal)-log10(MMcEvt.fEnergy)");
119// hres.InitName("ResTheta;Theta;EnergyResidual");
120// hres.InitTitle(";Zd [\\circ];\\Delta lg E;");
121// hres.SetDrawOption("colz profx");
122//
123// // Note that only AddHist is mandatory. All other options can be omitted
124//
125// // Initialize the filling task which can now be added to the tasklist
126// MFillH fill(&hres);
