LabeledArrow

Qualified name: manim.mobject.geometry.labeled.LabeledArrow

class LabeledArrow(*args, **kwargs)[source]

Bases: LabeledLine, Arrow

Constructs an arrow containing a label box somewhere along its length. This class inherits its label properties from LabeledLine, so the main parameters controlling it are the same.

Parameters:
  • label (str | Tex | MathTex | Text) – Label that will be displayed on the line.

  • label_position (float | optional) – A ratio in the range [0-1] to indicate the position of the label with respect to the length of the line. Default value is 0.5.

  • font_size (float | optional) – Control font size for the label. This parameter is only used when label is of type str.

  • label_color (ParsableManimColor | optional) – The color of the label’s text. This parameter is only used when label is of type str.

  • label_frame (Bool | optional) – Add a SurroundingRectangle frame to the label box.

  • frame_fill_color (ParsableManimColor | optional) – Background color to fill the label box. If no value is provided, the background color of the canvas will be used.

  • frame_fill_opacity (float | optional) – Determine the opacity of the label box by passing a value in the range [0-1], where 0 indicates complete transparency and 1 means full opacity.
