      categoryAnchor - the category anchor (null not permitted).
      labelAnchor - the label anchor (null not permitted).
      widthType - the width type (null not permitted).

    • CategoryLabelPosition

      public CategoryLabelPosition(RectangleAnchor categoryAnchor, TextBlockAnchor labelAnchor, TextAnchor rotationAnchor, double angle, CategoryLabelWidthType widthType, float widthRatio)

      Parameters:
      categoryAnchor - the category anchor (null not permitted).
      labelAnchor - the label anchor (null not permitted).
      rotationAnchor - the rotation anchor (null not permitted).
      angle - the rotation angle (null not permitted).
      widthType - the width type (null not permitted).
