Detailed Description

Interactive editor for an unbinned RooFit fit from RooFitUtils.

The fit and residual pads update live as parameters move. Parameters can be fixed or freed individually, bounds edited, and Refit re-runs the minimiser from the current values as starting points. The residual panel is marked with dashed guide lines at plus and minus three sigma.

Note: Normally reached through the Launch function below rather than constructed directly; the launcher owns the event loop, the batch-mode toggle and the X error-handler guard.

Warning: None of the objects passed in are owned by the editor, and all of them must outlive it. Accepting writes the edited values back into them in place.

Constructor & Destructor Documentation

◆ InteractiveRooFitEditor()

InteractiveRooFitEditor::InteractiveRooFitEditor	(	const TGWindow *	parent,
		TH1 *	hist,
		const std::vector< Double_t > *	events,
		Float_t	display_bin_width_kev,
		RooAbsPdf *	total_pdf,
		RooRealVar *	x,
		RooAbsData *	data,
		std::vector< RooFitPeakModel > *	peaks,
		RooFitBackgroundModel *	bkg,
		Double_t	range_low,
		Double_t	range_high,
		const TString &	info_label = "" )

Build the editor around a converged RooFit model.

Parameters

parent	Parent window, normally gClient->GetRoot().
hist	Display histogram. Borrowed.
events	Event-level values behind the histogram, so the display can be rebinned as the range changes. Borrowed.
display_bin_width_kev	Display bin width.
total_pdf	Summed model. Borrowed.
x	Observable. Borrowed.
data	Unbinned dataset. Borrowed.
peaks	Per-peak parameter models, edited in place.
bkg	Background model, edited in place.
range_low	Initial lower fit bound.
range_high	Initial upper fit bound.
info_label	Optional annotation shown in the editor.

Note: Moving the range slider rebuilds the display histogram from events, so binning follows the zoom. The fit itself stays unbinned.

◆ ~InteractiveRooFitEditor()

InteractiveRooFitEditor::~InteractiveRooFitEditor ( )

virtual

Destroys the widgets and drawing objects the editor created.

Member Function Documentation

◆ CloseWindow()

void InteractiveRooFitEditor::CloseWindow ( )

virtual

Window-manager close. Treated as a cancel, not an accept.

Definition at line 927 of file InteractiveRooFitEditor.cpp.

◆ GetEmbeddedCanvas()

TRootEmbeddedCanvas * InteractiveRooFitEditor::GetEmbeddedCanvas ( )

inline

The canvas holding the fit and residual pads.

Returns: Borrowed pointer; the editor owns it.

Definition at line 219 of file InteractiveRooFitEditor.hpp.

Referenced by LaunchInteractiveRooFitEditor().

◆ GetRedrawTimer()

TTimer * InteractiveRooFitEditor::GetRedrawTimer ( )

inline

The coalescing redraw timer, for the driving event loop.

Returns: Borrowed pointer; the editor owns it.

Definition at line 216 of file InteractiveRooFitEditor.hpp.

Referenced by LaunchInteractiveRooFitEditor().

◆ HandleTimer()

Bool_t InteractiveRooFitEditor::HandleTimer ( TTimer * timer )

virtual

Redraw tick.

Parameter edits set a dirty flag rather than redrawing inline; this coalesces them so dragging a slider does not queue one full redraw per pixel of travel.

Parameters

timer Timer that fired.
