Detailed Description

GUI for simple intuitive analysis of data in TTree ,.

Configure initial state of interface

In .kvrootrc file, user can configure the following options, corresponding to check boxes in the interface:

KVTreeAnalyzer.LogScale:         off
KVTreeAnalyzer.UserBinning:           off
KVTreeAnalyzer.UserWeight:       off
KVTreeAnalyzer.NewCanvas:      off
KVTreeAnalyzer.Normalize:      off
KVTreeAnalyzer.Stats:      off

Change value to 'on' if required.

Constructor & Destructor Documentation

◆ KVTreeAnalyzer() [1/2]

KVTreeAnalyzer::KVTreeAnalyzer ( Bool_t nogui = kTRUE )

◆ KVTreeAnalyzer() [2/2]

KVTreeAnalyzer::KVTreeAnalyzer	(	TTree *	t,
		Bool_t	nogui = `kFALSE`
	)

Initialize analyzer for a given TTree. (in fact we re-open the tree using a TChain) If 'nogui' option (default=kFALSE) is kTRUE we do not launch the graphical interface.

◆ DrawHisto()

void KVTreeAnalyzer::DrawHisto	(	TObject *	obj,
		Bool_t	gen = `kTRUE`
	)

Method called when a user double-clicks a histogram in the GUI list.

if histogram is already displayed in active pad and if the pad also contains a graphical contour (TCutG) object, we use the contour to define a new data selection (TEntryList) which is added to the internal list.
if 'reapply selection' is activated and if the current active selection is not the same as that used to generate the histogram, we generate a new histogram displaying the same variables but with the current selection.
if 'draw same' is active we superimpose the (1-D) spectrum on the existing plot with a different colour and add it to the automatically generated legend which is also displayed in the plot
if 'new canvas' is active the histogram is displayed in a new KVCanvas
in all cases when a histogram is displayed the log/linear scale of Y (1-D) or Z (2-D) axis is automatically adjusted according to the 'log scale' check box

		const Char_t *	selection,
		Int_t	nX,
		Int_t	nY = `0`,
		const Char_t *	weight = `""`,
		Double_t	xmin = `-1`,
		Double_t	xmax = `-1`,
		Double_t	ymin = `-1`,
		Double_t	ymax = `-1`
	)

Create and fill a new histogram with the desired expression (expr="expr1[:expr2]" etc.) with the given selection (selection="" if no selection required). Any currently active selection (TEntryList set on TTree) will also be applied. The new histogram is not drawn but added to the internal list of histograms (see method AddHisto).

Histograms are automatically named 'h1', 'h2', etc. in order of creation. Histogram title is generated with method GenerateHistoTitle. Number of bins on X (and Y for a 2-D spectrum) are given. Axis limits are automatically adjusted to data unless given.

For 2-D spectra the initial drawing option is set to "COL"

If normalisation of spectra is required (fNormHisto = kTRUE) the histogram bin contents are divided by the integral (sum of weights).

		const Char_t *	selection,

	)

Like MakeHisto but only used for 1-D spectra of integer variables. The number of bins is Xmax-Xmin+1 and bins are defined over [x-0.5,x+0.5] for all values of x.

Histograms are automatically named 'Ih1', 'Ih2', etc. in order of creation.

Definition at line 353 of file KVTreeAnalyzer.cpp.

◆ MakeSelection()

Bool_t KVTreeAnalyzer::MakeSelection ( const Char_t * selection )

Generate a new user-selection (TEntryList) of events in the TTree according to the given selection expression (valid TTreeFormula expression using TTree leaf and/or alias names). The new selection is not applied immediately but added to the internal list of selections (see method AddSelection).

If there is already an active selection (TEntryList set on TTree) this will generate the composite selection, {(active selection) && (selection)}. The selection's title will then be in the following format:

"[(active selection) && ](selection)"

TEntryList objects are automatically named 'el1', 'el2', etc. in order of creation.

◆ ReapplyAnyFile()

void KVTreeAnalyzer::ReapplyAnyFile ( const Char_t * filepath )

assuming filepath is the URL of a ROOT file, open it and, if no KVTreeAnalyzer object is found, open first TTree in file and apply all selections and generate all histograms which were made for this analysis. Any histograms in the file are added to the list of histograms. If filepath contains an existing analysis, we add to it any histograms/selections/aliases which are not defined

Definition at line 3199 of file KVTreeAnalyzer.cpp.

◆ RemakeHisto()

TH1 * KVTreeAnalyzer::RemakeHisto	(	TH1 *	h,
		const Char_t *	expr,
		const Char_t *	weight = `""`
	)

Remake an existing histogram of data 'expr' using the current active selection If such a histogram already exists, we just return its address. We must have the same binning in the new as in the original histogram.

Override TObject::SaveAs We need to:

(re)create the file
do fChain->SetDirectory before writing to disk save current directory

Reimplemented from TObject.

◆ SetSelection() [2/2]

void KVTreeAnalyzer::SetSelection ( TObject * obj )

Method called when a selection is double-clicked in the GUI list. The required selection is passed as argument (address of TEntryList object) and becomes the currently active selection (TEntryList set on TTree). If the requested selection was already active, it is deactivated (remove TEntryList from TTree). The 'CURRENT SELECTION' message in the GUI status bar is updated.

◆ SetTreeFileName()

void KVTreeAnalyzer::SetTreeFileName ( TTree * t )

the Tree file name is used as the basis for the default analysis backup filename. for a TChain there may be many files with a common root. we look for this common root and replace any "wildcard" characters with "X" i.e. for files "run_001.root", "run_002.root", ..., "run_999.root" we will use "Analysis_run_XXX.root" as default name
