Bases: GraphicsObject
Displays a line of infinite length. This line may be dragged to indicate a position in data coordinates.

Arguments | |
pos | Position of the line. This can be a QPointF or a single value for vertical/horizontal lines. |
angle | Angle of line in degrees. 0 is horizontal, 90 is vertical. |
pen | Pen to use when drawing line. Can be any arguments that are valid for mkPen. Default pen is transparent yellow. |
movable | If True, the line can be dragged to a new position by the user. |
bounds | Optional [min, max] bounding values. Bounds are only valid if the line is vertical or horizontal. |
Takes angle argument in degrees. 0 is horizontal; 90 is vertical.
Note that the use of value() and setValue() changes if the line is not vertical or horizontal.
Set the (minimum, maximum) allowable values when dragging.
Set whether the line is movable by the user.
Set the pen for drawing the line. Allowable arguments are any that are valid for mkPen.
Set the position of the line. If line is horizontal or vertical, v can be a single value. Otherwise, a 2D coordinate must be specified (list, tuple and QPointF are all acceptable).
Return the value of the line. Will be a single number for horizontal and vertical lines, and a list of [x,y] values for diagonal lines.
