Method Detail

createAndAddLabels

private void createAndAddLabels(javafx.scene.Group g,
                                javafx.geometry.Point2D centerPoint)

Create the labels and add them to the group.

Parameters:

g - group the labels are added to

centerPoint - central point around which the labels are placed.

snapToNearestAngle

void snapToNearestAngle()

Snap to the correct angle. Correct angle is angle belonging to the nearest label.

angleBetween2Lines

double angleBetween2Lines(javafx.geometry.Point2D center,
                          javafx.geometry.Point2D point)

Calculate the angle between the vector horizontally to the left from the center and the current point.

Parameters:

center - point

point - current point

Returns:

angle in degree

calculateSlope

double calculateSlope(javafx.geometry.Point2D center,
                      javafx.geometry.Point2D point)

Caluculate the slope of the line defined by two points. The first point is the center of a circle and the second point roughly lies on the circle.

Parameters:

center - point

point - on the circle

Returns:

slope of the connecting line.

calculateMoveFactor

double calculateMoveFactor(double angle)

Calculate the factor a label has to be moved based on the position on the curve.

Parameters:

angle - in degree in the range [0,180]

Returns:

move factor in the range [0,1]

calculateBasePoint

javafx.geometry.Point2D calculateBasePoint(javafx.geometry.Point2D center,
                                           double radius,
                                           double angle)

Calculate the base point for the label. This is the point on the arc, matching the angle.

Parameters:

center - point of the circle

radius - radius of the circle

angle - in degree in [0,180]

Returns:

Point on the circle
