LabelOrientation

Along

public const LabelOrientation Along

value = LabelOrientation.Along

The element's angle is always the same as the angle of the link's route at the segment where the element is attached. The element is turned to have the same angle as the route. Use this orientation for arrow heads.

Minus90

public const LabelOrientation Minus90

value = LabelOrientation.Minus90

The element's angle is always 90 degrees less than the angle of the link's route at the segment where the element is attached. The element is turned counter-clockwise to be perpendicular to the route.

Minus90Upright

public const LabelOrientation Minus90Upright

value = LabelOrientation.Minus90Upright

The element's angle is always 90 degrees less than the angle of the link's route at the segment where the element is attached, but is never upside down. The element is turned counter-clockwise to be perpendicular to the route, just like Minus90. This is typically only used for elements that contain text.

None

public const LabelOrientation None

value = LabelOrientation.None

The element is never rotated -- the angle is always zero.

Opposite

public const LabelOrientation Opposite

value = LabelOrientation.Opposite

The element's angle is always 180 degrees opposite from the angle of the link's route at the segment where the element is attached.

Plus90

public const LabelOrientation Plus90

value = LabelOrientation.Plus90

The element's angle is always 90 degrees more than the angle of the link's route at the segment where the element is attached. The element is turned clockwise to be perpendicular to the route.

Plus90Upright

public const LabelOrientation Plus90Upright

value = LabelOrientation.Plus90Upright

The element's angle is always 90 degrees more than the angle of the link's route at the segment where the element is attached, but is never upside down. The element is turned clockwise to be perpendicular to the route, just like Plus90. This is typically only used for elements that contain text.

Upright

public const LabelOrientation Upright

value = LabelOrientation.Upright

The element's angle always follows the angle of the link's route at the segment where the element is attached, but is never upside down. The element is turned to have the same angle as the route, just like Along. This is typically only used for elements that contain text.

Upright45

public const LabelOrientation Upright45

value = LabelOrientation.Upright45

The element's angle always follows the angle of the link's route at the segment where the element is attached, but is never upside down and is never angled more than +/- 45 degrees. When the route's angle is within 45 degrees of vertical (90 or 270 degrees), the element's angle is set to zero. This is typically only used for elements that contain text.
