TParallelCoord Class Reference

Parallel Coordinates class.

The multidimensional system of Parallel coordinates is a common way of studying high-dimensional geometry and visualizing multivariate problems. It has first been proposed by A. Inselberg in 1981.

To show a set of points in an n-dimensional space, a backdrop is drawn consisting of n parallel lines. A point in n-dimensional space is represented as a polyline with vertices on the parallel axes; the position of the vertex on the i-th axis corresponds to the i-th coordinate of the point.

This tool comes with a rather large gui in the editor. It is necessary to use this editor in order to explore a data set, as explained below.

Reduce cluttering:

The main issue for parallel coordinates is the very high cluttering of the output when dealing with large data set. Two techniques have been implemented to bypass that so far:

• Draw doted lines instead of plain lines with an adjustable dots spacing. A slider to adjust the dots spacing is available in the editor.
• Sort the entries to display with a "weight cut". On each axis is drawn a histogram describing the distribution of the data on the corresponding variable. The "weight" of an entry is the sum of the bin content of each bin the entry is going through. An entry going through the histograms peaks will have a big weight wether an entry going randomly through the histograms will have a rather small weight. Setting a cut on this weight allows to draw only the most representative entries. A slider set the cut is also available in the gui.

Selections:

Selections of specific entries can be defined over the data se using parallel coordinates. With that representation, a selection is an ensemble of ranges defined on the axes. Ranges defined on the same axis are conjugated with OR (an entry must be in one or the other ranges to be selected). Ranges on different axes are are conjugated with AND (an entry must be in all the ranges to be selected). Several selections can be defined with different colors. It is possible to generate an entry list from a given selection and apply it to the tree using the editor ("Apply to tree" button).

Axes:

Options can be defined each axis separately using the right mouse click. These options can be applied to every axes using the editor.

• Axis width: If set to 0, the axis is simply a line. If higher, a color histogram is drawn on the axis.
• Axis histogram height: If not 0, a usual bar histogram is drawn on the plot.

The order in which the variables are drawn is essential to see the clusters. The axes can be dragged to change their position. A zoom is also available. The logarithm scale is also available by right clicking on the axis.

Candle chart:

TParallelCoord can also be used to display a candle chart. In that mode, every variable is drawn in the same scale. The candle chart can be combined with the parallel coordinates mode, drawing the candle sticks over the axes.

{
   TCanvas *c1 = new TCanvas("c1");
   TFile *f = TFile::Open("cernstaff.root");
   TTree *T = (TTree*)f->Get("T");
   T->Draw("Age:Grade:Step:Cost:Division:Nation","","para");
   TParallelCoord* para = (TParallelCoord*)gPad->GetListOfPrimitives()->FindObject("ParaCoord");
   TParallelCoordVar* grade = (TParallelCoordVar*)para->GetVarList()->FindObject("Grade");
   grade->AddRange(new TParallelCoordRange(grade,11.5,14));
   para->AddSelection("less30");
   para->GetCurrentSelection()->SetLineColor(kViolet);
   TParallelCoordVar* age = (TParallelCoordVar*)para->GetVarList()->FindObject("Age");
   age->AddRange(new TParallelCoordRange(age,21,30));
}

Enumerator

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)

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.

CheckedHash()

ULong_t TObject::CheckedHash ( )

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.

ROOT::CallRecursiveRemoveIfNeeded(*this)

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.

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)

MayNotUse()

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

SaveAs()

void TObject::SaveAs ( const char * filename = "", Option_t * option = "" ) const

virtualinherited

Save this object in the file specified by filename.

• if "filename" contains ".root" the object is saved in filename as root binary file.
• if "filename" contains ".xml" the object is saved in filename as a xml ascii file.
• if "filename" contains ".cc" the object is saved in filename as C code independent from ROOT. The code is generated via SavePrimitive(). Specific code should be implemented in each object to handle this option. Like in TF1::SavePrimitive().

• otherwise the object is written to filename as a CINT/C++ script. The C++ code to rebuild this object is generated via SavePrimitive(). The "option" parameter is passed to SavePrimitive. By default it is an empty string. It can be used to specify the Draw option in the code generated by SavePrimitive.

  The function is available via the object context menu.

Definition at line 989 of file TObject.cxx.

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.
