|
|---|
| 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);
