Member Function Documentation

virtual const char* vtkPlotPoints::GetClassName ( ) [virtual]

Reimplemented from vtkPlot.

Reimplemented in vtkPlotLine.

static int vtkPlotPoints::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.

Reimplemented in vtkPlotLine.

virtual int vtkPlotPoints::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.

Reimplemented in vtkPlotLine.

static vtkPlotPoints* vtkPlotPoints::SafeDownCast ( vtkObject * o ) [static]

Reimplemented from vtkPlot.

Reimplemented in vtkPlotLine.

virtual void vtkPlotPoints::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.

Reimplemented in vtkPlotLine.

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

Creates a 2D Chart object.

Reimplemented from vtkObject.

Reimplemented in vtkPlotLine.

virtual void vtkPlotPoints::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 vtkContextItem.

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

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

Implements vtkContextItem.

Reimplemented in vtkPlotLine.

virtual bool vtkPlotPoints::PaintLegend	(	vtkContext2D *	painter,
		float	rect[4]
	)			`[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.

Reimplemented in vtkPlotLine.

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

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

Reimplemented from vtkPlot.

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

Function to query a plot for the nearest point to the specified coordinate.

Reimplemented from vtkPlot.

virtual bool vtkPlotPoints::SelectPoints	(	const vtkVector2f &	min,
		const vtkVector2f &	max
	)			`[virtual]`

Select all points in the specified rectangle.

Reimplemented from vtkPlot.

virtual int vtkPlotPoints::GetMarkerStyle ( ) [virtual]

Get/set the marker style that should be used. The default is none, the enum in this class is used as a parameter.

virtual void vtkPlotPoints::SetMarkerStyle ( int ) [virtual]

Get/set the marker style that should be used. The default is none, the enum in this class is used as a parameter.

void vtkPlotPoints::GeneraterMarker	(	int	width,
		bool	highlight = `false`
	)			`[protected]`

Generate the requested symbol for the plot

bool vtkPlotPoints::UpdateTableCache ( vtkTable * table ) [protected]

Update the table cache.

void vtkPlotPoints::CalculateLogSeries ( ) [protected]

Handle calculating the log of the x or y series if necessary. Should be called by UpdateTableCache once the data has been updated in Points.

void vtkPlotPoints::FindBadPoints ( ) [protected]

Find all of the "bad points" in the series. This is mainly used to cache bad points for performance reasons, but could also be used plot the bad points in the future.

void vtkPlotPoints::CalculateBounds ( double bounds[4] ) [protected]

Calculate the bounds of the plot, ignoring the bad points.
