void vtkChartXYZ::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 vtkObjectBase.

static vtkChartXYZ* vtkChartXYZ::New ( )

static

void vtkChartXYZ::SetGeometry ( const vtkRectf & bounds )

Set the geometry in pixel coordinates (origin and width/height).

This method also sets up the end points of the axes of the chart. For this reason, if you call SetAroundX(), you should call SetGeometry() afterwards.

void vtkChartXYZ::SetAngle ( double angle )

Set the rotation angle for the chart (AutoRotate mode only).

void vtkChartXYZ::SetAroundX ( bool isX )

Set whether or not we're rotating about the X axis.

virtual void vtkChartXYZ::SetAnnotationLink ( vtkAnnotationLink * link )

virtual

Set the vtkAnnotationLink for the chart.

vtkAxis* vtkChartXYZ::GetAxis ( int axis )

Get the x (0), y (1) or z (2) axis.

virtual void vtkChartXYZ::SetAxis	(	int	axisIndex,
		vtkAxis *	axis
	)

virtual

Set the x (0), y (1) or z (2) axis.

void vtkChartXYZ::SetAxisColor ( const vtkColor4ub & color )

Set the color for the axes.

vtkColor4ub vtkChartXYZ::GetAxisColor ( )

Set the color for the axes.

void vtkChartXYZ::SetAutoRotate ( bool b )

Set whether or not we're using this chart to rotate on a timer.

Set whether or not axes labels & tick marks should be drawn.

Default value is true.

void vtkChartXYZ::SetFitToScene ( bool b )

Set whether or not the chart should automatically resize itself to fill the scene.

Default value is true.

void vtkChartXYZ::Update ( )

overridevirtual

Perform any updates to the item that may be necessary before rendering.

Reimplemented from vtkAbstractContextItem.

bool vtkChartXYZ::Paint ( vtkContext2D * painter )

overridevirtual

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

Reimplemented from vtkAbstractContextItem.

virtual vtkIdType vtkChartXYZ::AddPlot ( vtkPlot3D * plot )

virtual

Adds a plot to the chart.

void vtkChartXYZ::ClearPlots ( )

Remove all the plots from this chart.

void vtkChartXYZ::RecalculateBounds ( )

Determine the XYZ bounds of the plots within this chart.

This information is then used to set the range of the axes.

void vtkChartXYZ::RecalculateTransform ( )

Use this chart's Geometry to set the endpoints of its axes.

This method also sets up a transformation that is used to properly render the data within the chart.

bool vtkChartXYZ::Hit ( const vtkContextMouseEvent & mouse )

overridevirtual

Returns true if the transform is interactive, false otherwise.

Reimplemented from vtkAbstractContextItem.

bool vtkChartXYZ::MouseButtonPressEvent ( const vtkContextMouseEvent & mouse )

overridevirtual

Mouse press event.

Keep track of zoom anchor position.

Reimplemented from vtkAbstractContextItem.

bool vtkChartXYZ::MouseMoveEvent ( const vtkContextMouseEvent & mouse )

overridevirtual

Mouse move event.

Perform pan or zoom as specified by the mouse bindings.

Reimplemented from vtkAbstractContextItem.

bool vtkChartXYZ::MouseWheelEvent	(	const vtkContextMouseEvent &	mouse,
		int	delta
	)

overridevirtual

Mouse wheel event.

Zooms in or out.

Reimplemented from vtkAbstractContextItem.

bool vtkChartXYZ::KeyPressEvent ( const vtkContextKeyEvent & key )

overridevirtual

Key press event.

This allows the user to snap the chart to one of three different 2D views. "x" changes the view so we're looking down the X axis. Similar behavior occurs for "y" or "z".

Reimplemented from vtkAbstractContextItem.

virtual void vtkChartXYZ::CalculateTransforms ( )

protectedvirtual

Calculate the transformation matrices used to draw data points and axes in the scene.

This function also sets up clipping planes that determine whether or not a data point is within range.

bool vtkChartXYZ::CalculatePlotTransform	(	vtkAxis *	x,
		vtkAxis *	y,
		vtkAxis *	z,
		vtkTransform *	transform
	)

protected

Given the x, y and z vtkAxis, and a transform, calculate the transform that the points in a chart would need to be drawn within the axes.

This assumes that the axes have the correct start and end positions, and that they are perpendicular.

bool vtkChartXYZ::Rotate ( const vtkContextMouseEvent & mouse )

protected

Rotate the chart in response to a mouse movement.

bool vtkChartXYZ::Pan ( const vtkContextMouseEvent & mouse )

protected

Pan the data within the chart in response to a mouse movement.

bool vtkChartXYZ::Zoom ( const vtkContextMouseEvent & mouse )

protected

Zoom in or out on the data in response to a mouse movement.

bool vtkChartXYZ::Spin ( const vtkContextMouseEvent & mouse )

protected

Spin the chart in response to a mouse movement.

void vtkChartXYZ::LookDownY ( )

protected

Adjust the rotation of the chart so that we are looking down the Y axis.

void vtkChartXYZ::LookDownZ ( )

protected

Adjust the rotation of the chart so that we are looking down the Z axis.

void vtkChartXYZ::LookUpX ( )

protected

Adjust the rotation of the chart so that we are looking up the X axis.

void vtkChartXYZ::LookUpY ( )

protected

Adjust the rotation of the chart so that we are looking up the Y axis.

void vtkChartXYZ::LookUpZ ( )

protected

Adjust the rotation of the chart so that we are looking up the Z axis.

bool vtkChartXYZ::CheckForSceneResize ( )

protected

Check to see if the scene changed size since the last render.

void vtkChartXYZ::RescaleAxes ( )

protected

Scale the axes up or down in response to a scene resize.

void vtkChartXYZ::ScaleUpAxes ( )

protected

Scale up the axes when the scene gets larger.

void vtkChartXYZ::ScaleDownAxes ( )

protected

Scale down the axes when the scene gets smaller.

void vtkChartXYZ::ZoomAxes ( int delta )

protected

Change the scaling of the axes by a specified amount.

void vtkChartXYZ::InitializeAxesBoundaryPoints ( )

protected

Initialize a list of "test points".

These are used to determine whether or not the chart fits completely within the bounds of the current scene.

void vtkChartXYZ::InitializeFutureBox ( )

protected

Initialize the "future box" transform.

This transform is a duplicate of the Box transform, which dictates how the chart's axes should be drawn. In ScaleUpAxes() and ScaleDownAxes(), we incrementally change the scaling of the FutureBox transform to determine how much we need to zoom in or zoom out to fit the chart within the newly resized scene. Using a separate transform for this process allows us to resize the Box in a single step.

void vtkChartXYZ::ComputeDataBounds ( )

protected

Compute a bounding box for the data that is rendered within the axes.

void vtkChartXYZ::DrawAxes ( vtkContext3D * context )

protected

Draw the cube axes of this chart.

void vtkChartXYZ::DetermineWhichAxesToLabel ( )

protected

For each of the XYZ dimensions, find the axis line that is furthest from the rendered data.

void vtkChartXYZ::DrawTickMarks ( vtkContext2D * painter )

protected

Draw tick marks and tick mark labels along the axes.

void vtkChartXYZ::DrawAxesLabels ( vtkContext2D * painter )

protected

Label the axes.

void vtkChartXYZ::GetOffsetForAxisLabel	(	int	axis,
		float *	bounds,
		float *	offset
	)

protected

Compute how some text should be offset from an axis.

The parameter bounds contains the bounding box of the text to be rendered. The result is stored in the parameter offset.

double vtkChartXYZ::CalculateNiceMinMax	(	double &	min,
		double &	max,
		int	axis
	)

protected
