      public PieLabelRecord​(Comparable key, double angle, double baseY, TextBox label, double labelHeight, double gap, double linkPercent)
      Creates a new record.
      Parameters:
      key - the section key.
      angle - the angle to the middle of the section (in radians).

    • setBaseY

      public void setBaseY​(double base)
      Sets the base y-coordinate.
      Parameters:
      base - the base y-coordinate.

    • getLowerY

      public double getLowerY()
      Returns the lower bound of the label.
      Returns:
      The lower bound.

    • getUpperY

      public double getUpperY()
      Returns the upper bound of the label.
      Returns:
      The upper bound.

    • getAngle

      Returns the angle of the middle of the section, in radians.
      Returns:
      The angle, in radians.

    • getKey

      public Comparable getKey()
      Returns the key for the section that the label applies to.
      Returns:
      The key.

    • getLabel

      public TextBox getLabel()
      Returns the label.
      Returns:
      The label.

    • getLabelHeight

      public double getLabelHeight()
      Returns the label height (you could derive this from the label itself, but we cache the value so it can be retrieved quickly).
      Returns:
      The label height (in Java2D units).

    • getAllocatedY

      public double getAllocatedY()
      Returns the allocated y-coordinate.
      Returns:
      The allocated y-coordinate.

    • setAllocatedY

      public void setAllocatedY​(double y)
      Sets the allocated y-coordinate.
      Parameters:
      y - the y-coordinate.

    • getGap

      public double getGap()
      Returns the gap.
      Returns:
      The gap.

    • getLinkPercent

      public double getLinkPercent()
