Detailed Description

Graphs that renew themselves iteratively to monitor a value.

As old points are to be deleted at a certain point, this has the appearance of a rolling counter.

Constructor & Destructor Documentation

◆ TGo4RollingGraph() [1/2]

TGo4RollingGraph::TGo4RollingGraph ( )

Default constructor.

Creates a rolling graph with an update interval of 1, i.e. no averaging of the input values Graph will have no size, either. Without setting size, nothing will be drawn!

Definition at line 23 of file TGo4RollingGraph.cxx.

◆ TGo4RollingGraph() [2/2]

TGo4RollingGraph::TGo4RollingGraph	(	Int_t	NumPoints,
		Int_t	UpdateInterval = `1`
	)

Constructor with size and update interval.

Parameters

NumPoints	Size of the graph, i.e. number of points
UpdateInterval	No. of calls to the Fill() routine after which a new bin will started to be filled. For UpdateInterval=1 every value will be displayed directly on the rolling graph, for values > 1 an average will be shown

Definition at line 33 of file TGo4RollingGraph.cxx.

◆ ~TGo4RollingGraph()

TGo4RollingGraph::~TGo4RollingGraph ( )

virtual

Destructor.

Definition at line 40 of file TGo4RollingGraph.cxx.

Member Function Documentation

◆ ClassDefOverride()

TGo4RollingGraph::ClassDefOverride	(	TGo4RollingGraph	,
		1
	)

protected

◆ Clear()

void TGo4RollingGraph::Clear ( Option_t * option = "" )

override

Clear all points.

Remove all points from the graph, set number of points to zero, and reset internal value for averaging

Definition at line 104 of file TGo4RollingGraph.cxx.

References ClassImp(), fdSum, and fiNumPoints.

◆ Fill()

void TGo4RollingGraph::Fill	(	Double_t	value,
		Double_t	xerror = `-1`,
		Double_t	yerror = `-1`
	)

virtual

Fills a new value into the rolling graph.

Parameters

value The value to fill

If the Update Interval is larger than one, the value will not be displayed directly in the graph but added to the averaging

◆ GetNumPoints()

Int_t TGo4RollingGraph::GetNumPoints ( ) const

inline

Returns number of displayed points.

Definition at line 35 of file TGo4RollingGraph.h.

References fiNumPoints.

◆ GetUpdateInterval()

Int_t TGo4RollingGraph::GetUpdateInterval ( ) const

inline

Returns interval of entries when a new bin is opened.

References fiUpdateInterval, and NextBin().

◆ NextBin()

void TGo4RollingGraph::NextBin ( )

protected

Create a new bin.

Internal function that implements the "rolling" of the graph: The first bin is deleted while a new one is appended at the end
