// PlotMillePede is a class to interprete the content of the ROOT
// TTrees that are stored as output of the millepede alignment algorithm.
// The histograms are created by the methods inherited from the
// MillePedeTrees class. Drawn quantities and selections are handled
// as strings as they can be understood by TTree::Draw(..) commands.
//
// The main methods all start with 'Draw', so you can use tab completion
// on what is available:
//     PlotMillePede p("treeFile.root"); // file form pede step
//     p.Draw<tab>
//
// Management of the created histograms is done using the ('ancient')
// class GFHistManager. A pointer to that class can be accessed by
//     GFHistManager *man = p.GetHistManager();
// and then be used manipulate the drawings, e.g. by  
//     man->SetLogY();
// or
//     man->SetNumHistsXY(3,1);
//     man->Draw();
//
// By calling new p.Draw..(..) commands, usually previously drawn canvases are
// deleted. But most methods provide either a boolean flag 'addPlots' or
// understand the option 'add'. If the flag is true or the option string
// contains 'add', canvases from previous Draw-commands are kept (in fact they
// are re-drawn).
//
// General Options
// ===============
// A title can be set by 'void SetTitle(const char *title)':
// The title will appear as part of all histogram titles.
//
// The x-axis ranges of many histograms can be controlled by calling one of
//   void SetMaxDev(Float_t maxDevDown, Float_t maxDevUp); // set x-axis range for result plots
//   void SetMaxDev(Float_t maxDev); // set symmetric x-axis range for result plots
// before calling a Draw-method. Similarly, the number of bins can be controlled via
//   Int_t SetNbins(Int_t nBins); // set number of bins for some result plots
// that returns the previous setting (default: 101)
//
// When drawing pede parameters using DrawPede<...>, the class cannot know
// what type of parameters that are, e.g. RigidBodyParameters or 
// (Two)BowedSurface(s)Parameters. To get correct axis labels and units you
// can switch between these two using p.SetBowsParameters(bool).
// If you do not choose, RigidBodyParameters are expected.
// 
// If something is plotted versus the radius, you can choose to use the signed
// radius instead that uses the sign of the y-coordinate:
// p.SetUseSignedR(bool)
//
// When drawing surface deformation values of double sensor modules (TOB, TEC R5-7),
// by default the bow parameters as stored in TwoBowedSurfacesDeformations are plotted,
// i.e. the average w_20, w_11, w_02 and their differences. You might want to see
// instead the full bow of sensor one and two instead, e.g. w_20^1 and w_20^2.
// This can be chosen by calling p.SetSurfDefDeltaBows(false).
//
//
// Alignable Selections
// ====================
// Several cuts can be set and are active until reset for all drawing routines
// called after setting them. Active selections are mentioned in histogram titles.
// The possibilites to set cuts are:
//
// 1) Select subdetector(s):
// void SetSubDetId(Int_t subDetId);
//  *  1-6 are TPB, TPE, TIB, TID, TOB, TEC, 
//  *  -1 means: reset, i.e. take all
//  * using (repeated) calls of
//    void AddSubDetId(Int_t subDetId);
//    leads to an OR selection of subdetectors
//  * can use void SetSubDetIds(Int_t id1, Int_t id2,
//                              Int_t id3 = -1, Int_t id4 = -1, Int_t id5 = -1);
//    i.e. call 'SetSubDetId(id1)' and subsequently AddSubDetId(id<n>) for all
//    n > 1 with id<n> > 0.
//
// 2) Special alignable types:
// Int_t SetAlignableTypeId(Int_t alignableTypeId);
//  * DetUnit=1,
//  * Det=2,
//  * TIBString=15,
//  * etc. from CommonAlignment/interface/StructureType.h 
//  * -1 resets
// The methods returns the previous setting.
//
// 3) Select hierarchy level:
// In case of hierarchical alignment, one can look at the parameters etc. of each 
// (active!) hierarchy level separately:
// Int_t SetHieraLevel(Int_t hieraLevel);
//  * 0 (default!): lowest level only
//  * 1,2,...: first, second,... larger structures only
//  * -1: resets, shows all levels
// The methods returns the previous setting.
//
// 4) General selection:
// void AddAdditionalSel(const char *selection);
//  * whatever selection string that is valid on the TTree's...
//  * ... therefore for experts 
//  * current setting cleared by 'ClearAdditionalSel()'
//
// 4a) Strip stereo, rphi, 1Dlayer/double sided selection:
//  * Known keywords for AddAdditionalSel(..)
//     * StripStereo:     only Id's of stereo modules in 2D layers/rings 
//     * StripRphi:       only Id's of rphi modules in 2D layers/rings 
//     * StripDoubleOr1D: only Id's from 1D layers or composed Dets in 2D layers/rings
//     * Not<one of above>: the opposite of the above three selections
//
// 4b) Geometrical and N(hit) selection:
// void AddAdditionalSel(const TString &xyzrPhiNhit, Float_t min, Float_t max);
//  This method makes internal use of the above "AddAdditionalSel(const char *)".
//  Selects quantity 'xyzrPhiNhit' between 'min' and 'max' where
//  'xyzrPhiNhit' can be any of x, y, z, r, phi, Nhit.
//  (Concerning 'Nhit' see also the comment about IOV handling below.)
//  Also cleared by 'ClearAdditionalSel()'.
//
// 5) Selecting predefined detector layers
// bool SetDetLayerCuts(unsigned int detLayer, bool silent = false);
//   This makes use of SetSubDetId(..) and AddAdditionalSel(..)
//   to select detector layers (or rings), e.g. TIB L1 stereo or TID R3.
//   Note this changes the internal state of cuts defined by previous calls
//   to these two methods! Therefore a warning is printed if such cuts are
//   set before. If this silent == true, this warning is suppressed.
//   Returns false if 'detLayer' not supported.
//
// 
// IOV handling
// ============
// In case of IOV dependent alignment, results are stored for each IOV.
// The second argument of the constructor decides which IOV is used.
// The default is 1 that is also valid in case there is no IOV dependence. 
// To draw the time dependence of parameters vs IOV numbers, use the class
// PlotMillePedeIOV.
//
// Note that the hit statistics is (unfortunately) counted without
// taking care of IOV boundaries, i.e. whatever IOV is chosen, the number of
// hits per alignable is always the same, i.e. the sum of all IOVs.
