Number Line

The defined number line VMobject in number_line.py

• Class NumberLine(Line)
• Class UnitInterval(NumberLine)

Class NumberLine(Line)

NumberLine is used to generate a number line for given parameters, color, x_min, x_max, unit_size, include_ticks, tick_size, tick_frequency, leftmost_tick,....

Example

Code

# folder/file: tut/manim_mobject_numberline_001a.py

from manimlib.scene.scene import Scene
from manimlib.mobject.number_line import NumberLine

class manim_mobject_numberline_001a(Scene): 
    def construct(self):
        num=NumberLine()
        self.add(num)
        self.wait(2)
        self.add(NumberLine(color="#FF3300",include_numbers=True,number_at_center=-2).rotate(0.5))
        self.wait(2)
        self.add(NumberLine(x_min=-4,x_max=4).rotate(1.5708))
        self.wait(2)
        self.add(NumberLine(x_min=-2,x_max=4).rotate(1.5708))
        self.wait(2)

Output

Class UnitInterval(NumberLine)

UnitInterval is used to generate an unit interval for given parameters.

Example

Code

# folder/file: tut/manim_mobject_unitinterval_001a.py

from manimlib.scene.scene import Scene
from manimlib.mobject.number_line import UnitInterval

class manim_mobject_unitinterval_001a(Scene): 
    def construct(self):
        num=UnitInterval()
        self.add(num)
        self.wait(2)
        self.add(UnitInterval(color="#FF3300").rotate(0.5))
        self.wait(2)
        self.add(UnitInterval(x_min=0,x_max=1,unit_size=0.5,include_numbers=True))
        self.wait(2)
        self.add(UnitInterval(color="#FF3300",x_min=-2,x_max=4,include_numbers=True).rotate(1.5708))
        self.wait(2)
