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!

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

~TGo4RollingGraph()

TGo4RollingGraph::~TGo4RollingGraph ( )

virtual

Destructor.

Member Function Documentation

ClassDefOverride()

TGo4RollingGraph::ClassDefOverride ( TGo4RollingGraph , 1  )

protected

References TGo4RollingGraph().

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 106 of file TGo4RollingGraph.cxx.

References 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
xerror	The X value
yerror	The Y value

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