Vector

Qualified name: manim.mobject.geometry.line.Vector

class Vector(direction=array([1., 0., 0.]), buff=0, **kwargs)

Bases: Arrow

A vector specialized for use in graphs.

Parameters

• direction (list | np.ndarray) – The direction of the arrow.

• buff (float) – The distance of the vector from its endpoints.

• kwargs – Additional arguments to be passed to Arrow

Examples

Example: VectorExample

from manim import *

class VectorExample(Scene):
    def construct(self):
        plane = NumberPlane()
        vector_1 = Vector([1,2])
        vector_2 = Vector([-5,-2])
        self.add(plane, vector_1, vector_2)

Methods

coordinate_label

Creates a label based on the coordinates of the vector.

Attributes

animate	Used to animate the application of any method of self.
animation_overrides
color
depth	The depth of the mobject.
fill_color	If there are multiple colors (for gradient) this returns the first one
height	The height of the mobject.
n_points_per_curve
sheen_factor
stroke_color
width	The width of the mobject.

coordinate_label(integer_labels=True, n_dim=2, color=None, **kwargs)

Creates a label based on the coordinates of the vector.

Parameters

• integer_labels (bool) – Whether or not to round the coordinates to integers.

• n_dim (int) – The number of dimensions of the vector.

• color (Color | None) – Sets the color of label, optional.

• kwargs – Additional arguments to be passed to Matrix.

Returns

The label.

Return type

Matrix

Examples

Example: VectorCoordinateLabel

from manim import *

class VectorCoordinateLabel(Scene):
    def construct(self):
        plane = NumberPlane()

        vec_1 = Vector([1, 2])
        vec_2 = Vector([-3, -2])
        label_1 = vec_1.coordinate_label()
        label_2 = vec_2.coordinate_label(color=YELLOW)

        self.add(plane, vec_1, vec_2, label_1, label_2)
