Plot frame and a container for graphics objects within that frame.

As a frame, it provides the TH1-style public interface for setting 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.

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer.

This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

Member Function Documentation

◆ AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning: This interface is a legacy function that is no longer recommended to be used by new development code.

Note: The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

Definition at line 1149 of file TObject.cxx.

◆ AddDirectory()

void RooPlot::AddDirectory ( bool add = true )

inlinestatic

Configure whether new instances of RooPlot will add themselves to gDirectory.

Like TH1::AddDirectory().

Definition at line 191 of file RooPlot.h.

◆ AddDirectoryStatus()

bool RooPlot::AddDirectoryStatus ( )

inlinestatic

Query whether new instances of RooPlot will add themselves to gDirectory.

When a file has been opened before a RooPlot instance is created, this instance will be associated to the file. Closing the file will e.g. write the instance to the file, and then delete it. Like TH1::AddDirectoryStatus().

Definition at line 199 of file RooPlot.h.

◆ addDirectoryStatus()

bool RooPlot::addDirectoryStatus ( )

static

Query whether new instances of RooPlot will add themselves to gDirectory.

When a file has been opened before a RooPlot instance is created, this instance will be associated to the file. Closing the file will e.g. write the instance to the file, and then delete it. Like TH1::AddDirectoryStatus().

Definition at line 77 of file RooPlot.cxx.

◆ addObject()

void RooPlot::addObject	(	TObject *	obj,
		Option_t *	drawOptions = "",
		bool	invisible = false )

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.

Definition at line 326 of file RooPlot.cxx.

◆ addPlotable()

void RooPlot::addPlotable	(	RooPlotable *	plotable,
		Option_t *	drawOptions = "",
		bool	invisible = false,
		bool	refreshNorm = false )

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.

Definition at line 476 of file RooPlot.cxx.

◆ addTH1()

void RooPlot::addTH1	(	TH1 *	hist,
		Option_t *	drawOptions = "",
		bool	invisible = false )

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.

Definition at line 345 of file RooPlot.cxx.

◆ AddToTObjectTable()

void TObject::AddToTObjectTable ( TObject * op )

staticprivateinherited

Private helper function which will dispatch to TObjectTable::AddObj.

◆ CheckedHash()

ULong_t TObject::CheckedHash ( )

inlineinherited

Check and record whether this class has a consistent Hash/RecursiveRemove setup (*) and then return the regular Hash value for this object.

The intent is for this routine to be called instead of directly calling the function Hash during "insert" operations. See TObject::HasInconsistenTObjectHash();

(*) The setup is consistent when all classes in the class hierarchy that overload TObject::Hash do call ROOT::CallRecursiveRemoveIfNeeded in their destructor. i.e. it is safe to call the Hash virtual function during the RecursiveRemove operation.

Definition at line 332 of file TObject.h.

◆ chiSquare() [1/2]

double RooPlot::chiSquare	(	const char *	curvename,
		const char *	histname,
		int	nFitParam = 0 ) const

Calculate and return reduced chi-squared between a curve and a histogram.

Parameters

[in]	curvename	Name of the curve or nullptr for last curve
[in]	histname	Name of the histogram to compare to or nullptr for last added histogram
[in]	nFitParam	If non-zero, reduce the number of degrees of freedom by this number. This means that the curve was fitted to the data with nFitParam floating parameters, which needs to be reflected in the calculation of \(\chi^2 / \mathrm{ndf}\).

Returns: \( \chi^2 / \mathrm{ndf} \) between the plotted curve and the data.

Note: The \( \chi^2 \) is calculated between a plot of the original distribution and the data. It therefore has more rounding errors than directly calculating the \( \chi^2 \) from a PDF or function. To do this, use RooAbsReal::createChi2(RooDataHist&, const RooCmdArg&, const RooCmdArg&, const RooCmdArg&, const RooCmdArg&, const RooCmdArg&, const RooCmdArg&, const RooCmdArg&, const RooCmdArg&).

Definition at line 1034 of file RooPlot.cxx.

◆ createInternalPlotVarClone()

void RooPlot::createInternalPlotVarClone ( )

Replaces the pointer to the plot variable with a pointer to a clone of the plot variable that is owned by this RooPlot.

The RooPlot references the plotted variable by non-owning pointer by default since ROOT 6.28, which resulted in a big speedup when plotting complicated pdfs that are expensive to clone. However, going back to an owned clone is useful in rare cases. For example in the RooUnitTest, where the registered plots need to live longer than the scope of the unit test.

◆ Hash()

ULong_t TNamed::Hash ( ) const

Return hash value for this object.

Note: If this routine is overloaded in a derived class, this derived class should also add

ROOT::CallRecursiveRemoveIfNeeded(*this)

ROOT::CallRecursiveRemoveIfNeeded

void CallRecursiveRemoveIfNeeded(TObject &obj)

call RecursiveRemove for obj if gROOT is valid and obj.TestBit(kMustCleanup) is true.

Definition TROOT.h:406

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides

TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

◆ HasInconsistentHash()

Bool_t TObject::HasInconsistentHash ( ) const

inlineinherited

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

◆ Write() [1/2]

◆ Write() [2/2]

Int_t TObject::Write	(	const char *	name = nullptr,
		Int_t	option = 0,
		Int_t	bufsize = 0 ) const

virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
The TBuffer object is filled via the class::Streamer function.
If the file is compressed (default) a second buffer is created to hold the compressed buffer.
Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.

Reimplemented in TBuffer, TCollection, TDirectory, TDirectoryFile, TFile, TMap, TParallelMergingFile, TSQLFile, TTree, and TXMLFile.
