Method Summary

Modifier and Type	Method	Description
protected String	axisLabel(int dimension)	Return the axis label for the given direction.
protected Coord2d	axisLabelOffset(IPainter painter, AxisRenderingInfo info, Coord3d labelPosition, int margin)	Offset for oblique labels.
protected Coord2d	axisLabelOffsetVertical(IPainter painter, AxisRenderingInfo info, Coord3d labelPosition, int margin)	Computes the offset to apply to a vertical Z label to avoid covering the tick labels in the case of a 3D chart.
protected Coord3d	axisLabelPosition(int direction, float tickLength, Coord3d pos, Coord3d dir)	Compute the axis label position according to the tick position (on the axis segment) and a direction for the tick.
protected Coord3d	axisLabelPosition_2D(int direction, Coord3d pos)	2D case : processed in 2D according to pixel margins, font size, and a pixel to world dimension ratio returned by the view
protected Coord3d	axisLabelPosition_3D(int direction, float tickLength, Coord3d pos, Coord3d dir)	3D case : process a shift from the center of the axis to annotate based on the tick length (hence distance between tick text and axis) and a distance factor of the axis label w.r.t.
protected float	axisLabelRotation(IPainter painter, int direction, Coord3d[] axisSegment)	Compute axis label rotation according to settings and direction of the axis segment.
protected void	drawAxisLabel(IPainter painter, int direction, Color color, BoundingBox3d ticksTxtBounds, Coord3d position, String label, float rotation, Coord2d offset)
protected TextAlign	getAxisLabelTextAlign(int direction)	Return an axis label alignment suitable for the type of chart : 3D, 2D XY, 2D XZ, 2D YZ

public AxisLabelProcessor(AxisBox axis)

Method Details

drawAxisLabel

protected void drawAxisLabel(IPainter painter,
 int direction,
 Color color,
 BoundingBox3d ticksTxtBounds,
 Coord3d position,
 String label,
 float rotation,
 Coord2d offset)

getAxisLabelTextAlign

protected TextAlign getAxisLabelTextAlign(int direction)

Return an axis label alignment suitable for the type of chart : 3D, 2D XY, 2D XZ, 2D YZ

axisLabelOffsetVertical

protected Coord2d axisLabelOffsetVertical(IPainter painter,
 AxisRenderingInfo info,
 Coord3d labelPosition,
 int margin)

Computes the offset to apply to a vertical Z label to avoid covering the tick labels in the case of a 3D chart. Retrieves pixel scale in view to adapt margin.

Parameters:

painter -

info -

labelPosition -

margin -

offset2D -

axisLabelOffset

protected Coord2d axisLabelOffset(IPainter painter,
 AxisRenderingInfo info,
 Coord3d labelPosition,
 int margin)

Offset for oblique labels.

Parameters:

painter -

info -

labelPosition -

margin -

Returns:

axisLabelRotation

protected float axisLabelRotation(IPainter painter,
 int direction,
 Coord3d[] axisSegment)

Compute axis label rotation according to settings and direction of the axis segment.

axisLabel

protected String axisLabel(int dimension)

Return the axis label for the given direction.

axisLabelPosition

protected Coord3d axisLabelPosition(int direction,
 float tickLength,
 Coord3d pos,
 Coord3d dir)

Compute the axis label position according to the tick position (on the axis segment) and a direction for the tick. This is quite intricated with View.computeCamera3D_RenderingSphere(Camera, ViewportConfiguration, BoundingBox3d) and View.computeCamera2D_RenderingSquare(Camera, ViewportConfiguration, BoundingBox3d) which will perform the actual camera configuration to ensure enough white space around the scene to draw the axis and tick labels

axisLabelPosition_2D

protected Coord3d axisLabelPosition_2D(int direction,
 Coord3d pos)

2D case : processed in 2D according to pixel margins, font size, and a pixel to world dimension ratio returned by the view

axisLabelPosition_3D

protected Coord3d axisLabelPosition_3D(int direction,
 float tickLength,
 Coord3d pos,
 Coord3d dir)

3D case : process a shift from the center of the axis to annotate based on the tick length (hence distance between tick text and axis) and a distance factor of the axis label w.r.t. the tick length
