void ProjectorBase::setNormalizing (  bool  on  )  [virtual, inherited]

Sets the scaling number of entries on if on is true, otherwise turns if off. Reimplemented in BinningProjector. Definition at line 362 of file ProjectorBase.cxx.

void ProjectorBase::setNumberOfBins (  hippodraw::Axes::Type  axis, unsigned int  number )  [virtual, inherited]

Sets the number of bins. Sets the number of bins along the axis axis to number. Not all projectors has a notation of a bin width. This interface is declared for those that do. The implementation in this base class is to does nothing. Reimplemented in MapMatrixProjector. Definition at line 221 of file ProjectorBase.cxx. Referenced by CompositePlotter::setNumberOfBins().

void ProjectorBase::setOffset (  hippodraw::Axes::Type  axis, double  offset )  [virtual, inherited]

Sets the bin offset. Sets the offset of bins by fraction offset of the bin width. Not all projectors has a notation of a bin width. This interface is declared for those that do. The implementation in this base class is to does nothing. Reimplemented in BinningProjector, Hist2DProjImp, MapMatrixProjector, and Profile2DProjector. Definition at line 246 of file ProjectorBase.cxx.

void ProjectorBase::setOffset (  const std::string &  axis, int  parm, bool  dragging )  [virtual, inherited]

Sets the bin offset. See also: setBinWidth ( const std::string &, int, bool ) Reimplemented in BinningProjector, DyHist2DProjector, and Profile2DProjector. Definition at line 238 of file ProjectorBase.cxx. Referenced by DisplayController::setOffset(), and CompositePlotter::setOffset().

void ProjectorBase::setRange (  hippodraw::Axes::Type  axis, bool  const_width = true )  [virtual, inherited]

Sets the range of the selected axis. The base class implementation only sets the dirty flag. Derived classes may need to do more. The option bool parameter if true indicates a binning projector should hold the bin width parameter constant. Reimplemented in FunctionProjector, Hist1DProjImp, Hist2DProjImp, Profile2DProjector, and ProfileProjector. Definition at line 133 of file ProjectorBase.cxx. References ProjectorBase::m_z_axis, ProjectorBase::setDirty(), hippodraw::Axes::X, hippodraw::Axes::Y, and hippodraw::Axes::Z. Referenced by DataRep::setRange().

void LineProjector::setValue (  double  value  )

Sets the value that will be projected. Definition at line 241 of file LineProjector.cxx. References m_value.

void ProjectorBase::update (  const Observable *   )  [virtual, inherited]

Implements the Observer pattern. The implementation in this abstract base class does nothing. Derived class may override this method if they are observers. Implements hippodraw::Observer. Reimplemented in BinningProjector, DyHist1DProjector, DyHist2DProjector, NTupleProjector, Profile2DProjector, and ProfileProjector. Definition at line 369 of file ProjectorBase.cxx.

Range LineProjector::valueRange (   )  const [virtual]

Finds the range of the projected values. It is up to derived classes to determine what this means. Todo: Resolve if this method should be here. Implements ProjectorBase. Definition at line 92 of file LineProjector.cxx. References ProjectorBase::getRange(), m_axis, ProjectorBase::m_x_axis, ProjectorBase::m_y_axis, and hippodraw::Axes::X.

bool ProjectorBase::wantsScaleFactor (  const std::string &  axis  )  const [virtual, inherited]

Returns whether the projector wants scale factor. Returns true if the projector wants to scale the axis, otherwise returns false. A projector supporting a histogram, for example, would want to scale the Y axis by the bin width in order to show entries per bin instead of density. This base class implementation always returns false. Reimplemented in Hist1DProjImp, and Hist2DProjImp. Definition at line 331 of file ProjectorBase.cxx. Referenced by CompositePlotter::checkAxisScaling().

void hippodraw::Observer::willDelete (  const Observable *   )  [virtual, inherited]

Notifies this Observer object that one of its Observable objects is about to be deleted. Since most Observable objects are owned by its Observer, it is the Observer that issued the delete. Thus the default implementation here does nothing. Derived classes that observe objects owned by another should implement this method to remove the Observable from the list they are observing. Reimplemented in FunctionRep, DataSourceController, CutPlotter, TextPlotter, BinningProjector, DyHist1DProjector, DyHist2DProjector, NTupleProjector, Profile2DProjector, and ProfileProjector.
