                             Coord2d offset)

axisLabelOffsetVertical

protected Coord2d axisLabelOffsetVertical(IPainter painter,
                                          AxisRenderingInfo info,

Return the axis label for the given direction.

axisLabelPosition

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

Compute the axis label position according to the tick position (on the axis segment) and a direction for the tick.
