Detailed Description

Class for drawing an XY line plot or bag given two columns from a vtkTable.

Depending on the number of components, this class will draw either a line plot (for 1 component column) or, for two components columns, a filled polygonal band (the bag) going from the first to the second component on the Y-axis along the X-axis. The filter vtkExtractFunctionalBagPlot is intended to create such "bag" columns.

Member Function Documentation

static int vtkPlotFunctionalBag::IsTypeOf ( const char * name ) [static]

Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPlot.

virtual int vtkPlotFunctionalBag::IsA ( const char * name ) [virtual]

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkPlot.

static vtkPlotFunctionalBag* vtkPlotFunctionalBag::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkPlot.

virtual vtkObjectBase* vtkPlotFunctionalBag::NewInstanceInternal ( ) const [protected, virtual]

Reimplemented from vtkPlot.

vtkPlotFunctionalBag* vtkPlotFunctionalBag::NewInstance ( ) const

Reimplemented from vtkPlot.

virtual void vtkPlotFunctionalBag::PrintSelf	(	ostream &	os,
		vtkIndent	indent
	)		`[virtual]`

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkPlot.

static vtkPlotFunctionalBag* vtkPlotFunctionalBag::New ( ) [static]

Creates a functional bag plot object.

Reimplemented from vtkObject.

virtual bool vtkPlotFunctionalBag::IsBag ( ) [virtual]

Returns true if the plot is a functional bag, false if it is a simple line.

virtual bool vtkPlotFunctionalBag::GetVisible ( ) [virtual]

Reimplemented to enforce visibility when selected.

Reimplemented from vtkAbstractContextItem.

virtual void vtkPlotFunctionalBag::Update ( ) [virtual]

Perform any updates to the item that may be necessary before rendering. The scene should take care of calling this on all items before their Paint function is invoked.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkPlotFunctionalBag::Paint ( vtkContext2D * painter ) [virtual]

Paint event for the plot, called whenever the chart needs to be drawn.

Reimplemented from vtkAbstractContextItem.

virtual bool vtkPlotFunctionalBag::PaintLegend	(	vtkContext2D *	painter,
		const vtkRectf &	rect,
		int	legendIndex
	)		`[virtual]`

Paint legend event for the plot, called whenever the legend needs the plot items symbol/mark/line drawn. A rect is supplied with the lower left corner of the rect (elements 0 and 1) and with width x height (elements 2 and 3). The plot can choose how to fill the space supplied.

Reimplemented from vtkPlot.

virtual void vtkPlotFunctionalBag::GetBounds ( double bounds[4] ) [virtual]

Get the bounds for this plot as (Xmin, Xmax, Ymin, Ymax).

Reimplemented from vtkPlot.

virtual void vtkPlotFunctionalBag::GetUnscaledInputBounds ( double bounds[4] ) [virtual]

Get the non-log-scaled bounds on chart inputs for this plot as (Xmin, Xmax, Ymin, Ymax).

Reimplemented from vtkPlot.

void vtkPlotFunctionalBag::SetLookupTable ( vtkScalarsToColors * lut )

Specify a lookup table for the mapper to use.

vtkScalarsToColors* vtkPlotFunctionalBag::GetLookupTable ( )

Specify a lookup table for the mapper to use.

virtual void vtkPlotFunctionalBag::CreateDefaultLookupTable ( ) [virtual]

Create default lookup table. Generally used to create one when none is available with the scalar data.

virtual vtkIdType vtkPlotFunctionalBag::GetNearestPoint	(	const vtkVector2f &	point,
		const vtkVector2f &	tolerance,
		vtkVector2f *	location
	)		`[virtual]`

Function to query a plot for the nearest point to the specified coordinate. Returns the index of the data series with which the point is associated or -1.

Reimplemented from vtkPlot.
