Detailed Description

A class to interpolate sparse, but continuous data in a TTree.

This was developed with adu5Pat variables like heading in mind. Not really necessary once full flight data is recovered.

Constructor & Destructor Documentation

Acclaim::FancyTTreeInterpolator::FancyTTreeInterpolator	(	TTree *	t,
		TString	xAxisText
	)

Constructor.

Parameters

t	is a TTree
xAxisText	is the name of a time-like branch in the TTree. realTime would be a good choice.

Does not presume to own t. If t s deleted out from under it, this class will fall over.

Definition at line 17 of file FancyTTreeInterpolator.cxx.

Acclaim::FancyTTreeInterpolator::~FancyTTreeInterpolator ( )

Desonstructor.

Deletes interally stored TGraphs.

Member Function Documentation

void Acclaim::FancyTTreeInterpolator::add ( TString yAxisText )

Adds a TGraph to the interally stored TGraphs.

Parameters

yAxisText is defines the y-axis of the TGraph, drawn against fXaxisText

Definition at line 183 of file FancyTTreeInterpolator.cxx.

void Acclaim::FancyTTreeInterpolator::add	(	TString	yAxisText,
		TString	cutString
	)

Adds a TGraph to the interally stored TGraphs.

Parameters

yAxisText	is defines the y-axis of the TGraph, drawn against fXaxisText
cutString	defines the cuts to padd to fTree->Draw();

Definition at line 197 of file FancyTTreeInterpolator.cxx.

void Acclaim::FancyTTreeInterpolator::add	(	TString	yAxisText,
		Double_t	wrapValue
	)

Adds a TGraph to the interally stored TGraphs.

Parameters

yAxisText	is defines the y-axis of the TGraph, drawn against fXaxisText
wrapValue	value to unwrap around. e.g. 360 for rotations in degrees.

Definition at line 212 of file FancyTTreeInterpolator.cxx.

void Acclaim::FancyTTreeInterpolator::add	(	TString	yAxisText,
		TString	cutString,
		Double_t	wrapValue
	)

Adds a TGraph to the interally stored TGraphs.

Parameters

yAxisText	is defines the y-axis of the TGraph, drawn against fXaxisText
cutString	defines the cuts to padd to fTree->Draw();
wrapValue	value to unwrap around. e.g. 360 for rotations in degrees.

Definition at line 228 of file FancyTTreeInterpolator.cxx.

TGraph * Acclaim::FancyTTreeInterpolator::get ( TString yAxisText )

Access the interally stored TGraph via the yAxisText.

Parameters

yAxisText is defines the y-axis of the TGraph, drawn against fXaxisText

Returns: A pointer to accessed TGraph, returns NULL if no match is found.

Definition at line 246 of file FancyTTreeInterpolator.cxx.

Double_t Acclaim::FancyTTreeInterpolator::interp	(	TString	yAxisText,
		Double_t	xAxisValue
	)

Get interpolated yAxisText variable at xAxisValue (time).

Parameters

yAxisText	is defines the y-axis of the TGraph, drawn against fXaxisText
xAxisValue	is the value of the fXaxisText branch to interpolate the yAxisText branch variable at.

Returns: the interpolated value.

Definition at line 273 of file FancyTTreeInterpolator.cxx.

TGraph * Acclaim::FancyTTreeInterpolator::makeSortedTGraph ( TString drawText )

Makes a sorted TGraph from fTree->Draw() with no cuts.

Parameters

drawText is the text to pass to fTree::Draw();

Returns: a pointer to the created, sorted TGraph.

Definition at line 64 of file FancyTTreeInterpolator.cxx.

TGraph * Acclaim::FancyTTreeInterpolator::makeSortedTGraph	(	TString	drawText,
		TString	cutString
	)

Makes a sorted TGraph from fTree->Draw() with cuts.

Parameters

drawText	is the text to pass to fTree->Draw();
cutString	defines the cuts to padd to fTree->Draw();

Returns: a pointer to the created, sorted TGraph.

Definition at line 79 of file FancyTTreeInterpolator.cxx.

TGraph * Acclaim::FancyTTreeInterpolator::makeSortedTGraph	(	TString	drawText,
		Double_t	wrapValue
	)

Makes a sorted TGraph from fTree->Draw() with no cuts.

Parameters

drawText	is the text to pass to fTree->Draw();
wrapValue	value to unwrap around. e.g. 360 for rotations in degrees.

Returns: a pointer to the created, sorted TGraph.

For example if you want to interpolate between 359 and 1 degrees, these will be unwrapped as 259, 361. These values can then be interpolated between correctly.

Definition at line 98 of file FancyTTreeInterpolator.cxx.
