Member Function Documentation

IsTypeOf()

static vtkTypeBool vtkPlotLine::IsTypeOf ( const char *  type )

static

IsA()

virtual vtkTypeBool vtkPlotLine::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 vtkPlotPoints.

SafeDownCast()

static vtkPlotLine * vtkPlotLine::SafeDownCast ( vtkObjectBase *  o )

static

NewInstanceInternal()

virtual vtkObjectBase * vtkPlotLine::NewInstanceInternal ( ) const

protectedvirtual

Reimplemented from vtkPlotPoints.

NewInstance()

vtkPlotLine * vtkPlotLine::NewInstance

(

const

PrintSelf()

void vtkPlotLine::PrintSelf ( ostream &  os, vtkIndent  indent  )

overridevirtual

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.

New()

static vtkPlotLine * vtkPlotLine::New ( )

static

Creates a 2D Chart object.

Paint()

bool vtkPlotLine::Paint ( vtkContext2D *  painter )

overridevirtual

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

Reimplemented from vtkAbstractContextItem.

PaintLegend()

bool vtkPlotLine::PaintLegend ( vtkContext2D *  painter, const vtkRectf &  rect, int  legendIndex  )

overridevirtual

Paint legend event for the XY 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.

SetPolyLine()

virtual void vtkPlotLine::SetPolyLine ( bool  )

virtual

Turn on/off flag to control whether the points define a poly line (true) or multiple line segments (false).

If true (default), a segment is drawn between each points (e.g. [P1P2, P2P3, P3P4...].) If false, a segment is drawn for each pair of points (e.g. [P1P2, P3P4,...].)

GetPolyLine()

virtual bool vtkPlotLine::GetPolyLine ( )

virtual

Turn on/off flag to control whether the points define a poly line (true) or multiple line segments (false).

If true (default), a segment is drawn between each points (e.g. [P1P2, P2P3, P3P4...].) If false, a segment is drawn for each pair of points (e.g. [P1P2, P3P4,...].)

PolyLineOn()

virtual void vtkPlotLine::PolyLineOn ( )

virtual

Turn on/off flag to control whether the points define a poly line (true) or multiple line segments (false).

If true (default), a segment is drawn between each points (e.g. [P1P2, P2P3, P3P4...].) If false, a segment is drawn for each pair of points (e.g. [P1P2, P3P4,...].)

PolyLineOff()

virtual void vtkPlotLine::PolyLineOff ( )

virtual

Turn on/off flag to control whether the points define a poly line (true) or multiple line segments (false).

If true (default), a segment is drawn between each points (e.g. [P1P2, P2P3, P3P4...].) If false, a segment is drawn for each pair of points (e.g. [P1P2, P3P4,...].)
