26//
27// MH3
28//
29// With this histogram you can fill a histogram with up to three
30// variables from Mars parameter containers in an eventloop.
31//
32// In the constructor you can give up to three variables which should be
33// filled in the histogram. Dependend on the number of given variables
34// (data members) a TH1D, TH2D or TH3D is created.
35// Specify the data mamber like the following:
36// "MHillas.fLength"
37// Where MHillas is the name of the parameter container in the parameter
38// list and fLength is the name of the data member which should be filled
39// in the histogram. Assuming that your MHillas container has a different
40// name (MyHillas) the name to give would be:
41// "MyHillas.fLength"
42//
43// If you want to use a different unit for histogramming use SetScaleX,
44// SetScaleY and SetScaleZ.
45//
46//
47// Binning/Binning name
48// =====================
49//
50// The axis binning is retrieved from the parameter list, too. Create a
51// MBinning with the name "Binning" plus the name of your MH3 container
52// plus the axis name ("X", "Y" or "Z") and add it to the parameter list.
53//
54// If the binning should have a different name than the histogram name
55// the binning name can be added to the name, eg.:
56// SetName("MyHistName;MyXBins;MyYBins")
57// Instead of BinningMyHistName[XYZ] the parameter list will be searched
58// for BinningMyXBinning, BinningMyYBins and BinningMyHistNameZ
59//
60// If you don't want to use a MBinning object from the parameter list
61// you can also set one directly, for example
62// MBinning bins(10, 0, 1);
63// mh3.SetBinningX(&bins);
64// You must not delete the MBinning object before the class has been
65// PreProcessed.
66//
67//
68// Axis titles
69// ===========
70//
71// 1) If no other title is given the rule for this axis is used.
72// 2) If the MBinning used for this axis has a non-default Title
73// (MBinning::HasTitle) this title is used for the corresponding axis
74// 3) If the MH3 has a non-default title (MH3::SetTitle called)
75// this title is set as the histogram title. It can be used to overwrite
76// the axis titles. For more information see TH1::SetTitle, eg.
77// SetTitle("MyHist;x[mm];y[cm];Counts");
78//
79//
80// Labels
81// ======
82//
83// To use labels at an axis you have to initialize this for the axis
84// by either calling InitLabels(Labels_t) or setiting a DefaultLabel.
85// For the axis for which the labels have been initialized the
86// number returned by the given corresponding phrase is converted
87// to int with TMath::Nint and used as a label. If you want to replace
88// this id by a named label you can call DefineLabel to do that.
89// Several ids can be replaced by the same label. If you define
90// named labels for every label which was not defined the default
91// is used, if any, otherwise an unnamed label is created.
92//
93// In the case of an axis with labels the axis-title cannot be
94// set via a MBinning, because the MBinning is not evaluated.
95//
96// Please note that for some reason not all combinations of
97// labels, dimensions and weights are available in the root-
98// histogram classes. Please check the MH3::Fill function to see
99// whether your combination is supported.
100//
101//
102// Examples:
103// =========
104//
105// 1) MH3 myhist("MHillas.fLength");
106// myhist.SetName("MyHist");
107// myhist.SetScaleX(geomcam.GetConvMm2Deg()); //convert length to degree
108// MBinning bins("BinningMyHistX", "Title for my x-axis [Hz]");
109// bins.SetEdges(10, 0, 150);
110// plist.AddToList(&bins);
111//
112// 2) MH3 myhist("MHillas.fLength");
113// myhist.SetName("MyHist;MyX");
114// myhist.SetTitle("Histogram Title;X-Title [mm];Counts");
115// MBinning bins("BinningMyX");
116// bins.SetEdges(10, 0, 150);
117// plist.AddToList(&bins);
118//
119// 3) MH3 myhist("MTriggerPatter.GetUnprescaled");
120// myhist.SetWeight("1./MRawRunHeader.GetRunLength");
121// myhist.SetTitle("Rate of the trigger pattern [Hz];Run Number;Trigger Pattern;Rate [Hz]");
122// myhist.InitLabels(MH3::kLabelsXY);
123// myhist.DefaultLabelY("UNKNOWN"); // Lvl1
124// myhist.DefineLabelY( 1, "Trig"); // Lvl1
125// myhist.DefineLabelY( 2, "Cal"); // Cal
126// myhist.DefineLabelY( 4, "Trig"); // Lvl2
127// myhist.DefineLabelY( 8, "Ped"); // Ped
