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 TH1F, TH2F or TH3F 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// The axis binning is retrieved from the parameter list, too. Create a
44// MBinning with the name "Binning" plus the name of your MH3 container
45// plus the axis name ("X", "Y" or "Z") and add it to the parameter list.
46//
47// If you want to use a different unit for histogramming use SetScaleX,
48// SetScaleY and SetScaleZ.
49//
50//
51// Axis titles
52// ===========
53//
54// 1) If no other title is given the rule for this axis is used.
55// 2) If the MBinning used for this axis has a non-default Title
56// (MBinning::HasTitle) this title is used for the corresponding axis
57// 3) If the MH3 has a non-default title (MH3::SetTitle called)
58// this title is set as the histogram title. It can be used to overwrite
59// the axis titles. For more information see TH1::SetTitle, eg.
60// SetTitle("MyHist;x[mm];y[cm];Counts");
61//
62// For example:
63// MH3 myhist("MHillas.fLength");
64// myhist.SetName("MyHist");
65// myhist.SetScaleX(geomcam.GetConvMm2Deg()); //convert length to degree
66// MBinning bins("BinningMyHistX");
67// bins.SetEdges(10, 0, 150);
68// plist.AddToList(&myhist);
69// plist.AddToList(&bins);
