Member Function Documentation

static int vtkPlotBar::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 vtkPlotBar::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 vtkPlotBar* vtkPlotBar::SafeDownCast ( vtkObjectBase * o ) [static]

Reimplemented from vtkPlot.

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

Reimplemented from vtkPlot.

vtkPlotBar* vtkPlotBar::NewInstance ( ) const

Reimplemented from vtkPlot.

virtual void vtkPlotBar::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 vtkPlotBar* vtkPlotBar::New ( ) [static]

Creates a 2D Chart object.

Reimplemented from vtkObject.

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

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

Reimplemented from vtkAbstractContextItem.

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

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.

virtual void vtkPlotBar::SetColor	(	unsigned char	r,
		unsigned char	g,
		unsigned char	b,
		unsigned char	a
	)		`[virtual]`

Set the plot color

Reimplemented from vtkPlot.

virtual void vtkPlotBar::SetColor	(	double	r,
		double	g,
		double	b
	)		`[virtual]`

Set the plot color

Reimplemented from vtkPlot.

virtual void vtkPlotBar::GetColor ( double rgb[3] ) [virtual]

Set the plot color

Reimplemented from vtkPlot.

virtual void vtkPlotBar::SetWidth ( float ) [virtual]

Set the width of the line.

Reimplemented from vtkPlot.

virtual float vtkPlotBar::GetWidth ( ) [virtual]

Get the width of the line.

Reimplemented from vtkPlot.

virtual void vtkPlotBar::SetOffset ( float ) [virtual]

Set/get the horizontal offset of the bars. Positive values move the bars leftward. For HORIZONTAL orientation, offsets bars vertically, with a positive value moving bars downward.

virtual float vtkPlotBar::GetOffset ( ) [virtual]

Set/get the horizontal offset of the bars. Positive values move the bars leftward. For HORIZONTAL orientation, offsets bars vertically, with a positive value moving bars downward.

virtual void vtkPlotBar::SetOrientation ( int orientation ) [virtual]

Set/get the orientation of the bars. Valid orientations are VERTICAL (default) and HORIZONTAL.

virtual int vtkPlotBar::GetOrientation ( ) [virtual]

Set/get the orientation of the bars. Valid orientations are VERTICAL (default) and HORIZONTAL.

virtual void vtkPlotBar::GetBounds	(	double	bounds[4],
		bool	unscaled
	)		`[virtual]`

A helper used by both GetUnscaledBounds and GetBounds(double[4]).

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

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

Reimplemented from vtkPlot.

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

Get un-log-scaled bounds for this mapper as (Xmin,Xmax,Ymin,Ymax).

Reimplemented from vtkPlot.

virtual void vtkPlotBar::SetInputArray	(	int	index,
		const vtkStdString &	name
	)		`[virtual]`

When used to set additional arrays, stacked bars are created.

Reimplemented from vtkPlot.

void vtkPlotBar::SetColorSeries ( vtkColorSeries * colorSeries )

Set the color series to use if this becomes a stacked bar plot.

vtkColorSeries* vtkPlotBar::GetColorSeries ( )

Get the color series used if when this is a stacked bar plot.

virtual vtkStringArray* vtkPlotBar::GetLabels ( ) [virtual]

Get the plot labels.
