class RooPlot: public TNamed, public RooPrintable



A RooPlot is a plot frame and a container for graphics objects within that frame. As a frame, it provides the TH1-style public interface for settting plot ranges, configuring axes, etc. As a container, it holds an arbitrary set of objects that might be histograms of data, curves representing a fit model, or text labels. Use the Draw() method to draw a frame and the objects it contains. Use the various add...() methods to add objects to be drawn. In general, the add...() methods create a private copy of the object you pass them and return a pointer to this copy. The caller owns the input object and this class owns the returned object.

All RooAbsReal and RooAbsData derived classes implement plotOn() functions that facilitate to plot themselves on a given RooPlot, e.g.

 RooPlot *frame = x.frame() ;
 data.plotOn(frame) ;
 pdf.plotOn(frame) ;
 
These high level functions also take care of any projections or other mappings that need to be made to plot a multi-dimensional object onto a one-dimensional plot.

TString histName()

~RooPlot()
 Destructor
void updateNormVars(const RooArgSet& vars)
 Install the given set of observables are reference normalization
 variables for this frame. These observables are e.g. later used
 to automatically project out observables when plotting functions
 on this frame. This function is only effective when called the
 first time on a frame
Stat_t GetBinContent(Int_t ) const
 A plot object is a frame without any bin contents of its own so this
 method always returns zero.
Stat_t GetBinContent(Int_t , Int_t ) const
 A plot object is a frame without any bin contents of its own so this
 method always returns zero.
Stat_t GetBinContent(Int_t , Int_t , Int_t ) const
 A plot object is a frame without any bin contents of its own so this
 method always returns zero.
void addObject(TObject* obj, Option_t* drawOptions = "", Bool_t invisible = kFALSE)
 Add a generic object to this plot. The specified options will be
 used to Draw() this object later. The caller transfers ownership
 of the object with this call, and the object will be deleted
 when its containing plot object is destroyed.
void addTH1(TH1* hist, Option_t* drawOptions = "", Bool_t invisible = kFALSE)
 Add a TH1 histogram object to this plot. The specified options
 will be used to Draw() this object later. "SAME" will be added to
 the options if they are not already present. The caller transfers
 ownership of the object with this call, and the object will be
 deleted when its containing plot object is destroyed.
void addPlotable(RooPlotable* plotable, Option_t* drawOptions = "", Bool_t invisible = kFALSE, Bool_t refreshNorm = kFALSE)
 Add the specified plotable object to our plot. Increase our y-axis
 limits to fit this object if necessary. The default lower-limit
 is zero unless we are plotting an object that takes on negative values.
 This call transfers ownership of the plotable object to this class.
 The plotable object will be deleted when this plot object is deleted.
void updateFitRangeNorm(const TH1* hist)
 Update our plot normalization over our plot variable's fit range,
 which will be determined by the first suitable object added to our plot.
void updateFitRangeNorm(const RooPlotable* rp, Bool_t refeshNorm = kFALSE)
 Update our plot normalization over our plot variable's fit range,
 which will be determined by the first suitable object added to our plot.
void updateYAxis(Double_t ymin, Double_t ymax, const char* label = "")
 Update our y-axis limits to accomodate an object whose spread
 in y is (ymin,ymax). Use the specified y-axis label if we don't
 have one assigned already.
void Draw(Option_t* options = 0)
 Draw this plot and all of the elements it contains. The specified options
 only apply to the drawing of our frame. The options specified in our add...()
 methods will be used to draw each object we contain.
void printName(ostream& os) const
 Print frame name
void printTitle(ostream& os) const
 Print frame title
void printClassName(ostream& os) const
 Print frame class name
void printArgs(ostream& os) const
void printValue(ostream& os) const
 Print frame arguments
void printMultiline(ostream& os, Int_t content, Bool_t verbose = kFALSE, TString indent = "") const
 Frame detailed printing
const char* nameOf(Int_t idx) const
 Return the name of the object at slot 'idx' in this RooPlot.
 If the given index is out of range, return a null pointer
TObject* getObject(Int_t idx) const
 Return the name of the object at slot 'idx' in this RooPlot.
 If the given index is out of range, return a null pointer
TAttLine * getAttLine(const char* name = 0) const
 Return a pointer to the line attributes of the named object in this plot,
 or zero if the named object does not exist or does not have line attributes.
TAttFill * getAttFill(const char* name = 0) const
 Return a pointer to the fill attributes of the named object in this plot,
 or zero if the named object does not exist or does not have fill attributes.
TAttMarker * getAttMarker(const char* name = 0) const
 Return a pointer to the marker attributes of the named object in this plot,
 or zero if the named object does not exist or does not have marker attributes.
TAttText * getAttText(const char* name = 0) const
 Return a pointer to the text attributes of the named object in this plot,
 or zero if the named object does not exist or does not have text attributes.
RooCurve* getCurve(const char* name = 0) const
 Return a RooCurve pointer of the named object in this plot,
 or zero if the named object does not exist or is not a RooCurve
RooHist* getHist(const char* name = 0) const
 Return a RooCurve pointer of the named object in this plot,
 or zero if the named object does not exist or is not a RooCurve
Bool_t drawBefore(const char* before, const char* target)
 Change the order in which our contained objects are drawn so that
 the target object is drawn just before the specified object.
 Returns kFALSE if either object does not exist.
Bool_t drawAfter(const char* after, const char* target)
 Change the order in which our contained objects are drawn so that
 the target object is drawn just after the specified object.
 Returns kFALSE if either object does not exist.
TObject * findObject(const char* name, const TClass* clas = 0) const
 Find the named object in our list of items and return a pointer
 to it. Return zero and print a warning message if the named
 object cannot be found. If no name is supplied the last object
 added is returned.

 Note that the returned pointer is to a
 TObject and so will generally need casting. Use the getAtt...()
 methods to change the drawing style attributes of a contained
 object directly.
TString getDrawOptions(const char* name) const
 Return the Draw() options registered for the named object. Return
 an empty string if the named object cannot be found.
Bool_t setDrawOptions(const char* name, TString options)
 Register the specified drawing options for the named object.
 Return kFALSE if the named object cannot be found.
Bool_t getInvisible(const char* name) const
 Returns true of object with given name is set to be invisible
void setInvisible(const char* name, Bool_t flag = kTRUE)
 If flag is true object with 'name' is set to be invisible
 i.e. it is not drawn when Draw() is called

 Utility function
void SetMaximum(Double_t maximum = -1111)
 Set maximum value of Y axis
void SetMinimum(Double_t minimum = -1111)
 Set minimum value of Y axis
Double_t chiSquare(const char* pdfname, const char* histname, int nFitParam = 0) const
 Calculate and return reduced chi-squared of curve with given name with respect
 to histogram with given name. If nFitParam is non-zero, it is used to reduce the
 number of degrees of freedom for a chi^2 for a curve that was fitted to the
 data with that number of floating parameters
RooHist* residHist(const char* histname = 0, const char* pdfname = 0, bool normalize = false) const
 Return a RooHist containing the residuals of histogram 'histname' with respect
 to curve 'curvename'. If normalize is true the residuals are divided by the error
 on the histogram, effectively returning a pull histogram
Double_t getFitRangeNEvt(Double_t xlo, Double_t xhi) const
 Return the number of events that is associated with the range [xlo,xhi]
 This method is only fully functional for ranges not equal to the full
 range if the object that inserted the normalization data provided
 a link to an external object that can calculate the event count in
 in sub ranges. An error will be printed if this function is used
 on sub-ranges while that information is not available
void SetName(const char* name)
 Set the name of the RooPlot to 'name'
void SetNameTitle(const char* name, const char* title)
 Set the name and title of the RooPlot to 'name' and 'title'
