Probability

The defined probability VMobject in probability.py

• Class SampleSpace(Rectangle)
• Class BarChart(VGroup)

Class SampleSpace(Rectangle)

SampleSpace is used to generate a sample space Mobject for given parameters.

Example

Code

# folder/file: tut/manim_mobject_samplespace_001a.py

from manimlib.scene.scene import Scene
from manimlib.mobject.probability import SampleSpace
from manimlib.animation.creation import ShowCreation

class manim_mobject_samplespace_001a(Scene):
    def construct(self):
        poly = SampleSpace(stroke_width=15,color="#88FF00",fill_color="#FFFF00",fill_opacity=1)
        poly.add_title()
        self.play(ShowCreation(poly),run_time=2)
        self.play(ShowCreation(SampleSpace(width=1.5,height=2,color="#000000").move_to([-4,0,0])),run_time=2)
        self.play(ShowCreation(SampleSpace(width=3,height=1,color="#008800").move_to([4,0,0])),run_time=2)
        self.play(ShowCreation(SampleSpace().move_to([-6,0,0]).scale(0.5)),run_time=2)

Output

Class BarChart(VGroup)

BarChart is used to generate a bar chart Mobject of specified values for given parameters.

Example

Code

# folder/file: tut/manim_mobject_barchart_001a.py

from manimlib.scene.scene import Scene
from manimlib.mobject.probability import BarChart
from manimlib.animation.creation import ShowCreation

class manim_mobject_barchart_001a(Scene):
    def construct(self):
        poly = BarChart([1,2,3],stroke_width=15,color="#88FF00",fill_color="#FFFF00",fill_opacity=1)
        self.play(ShowCreation(poly),run_time=2)
        self.play(ShowCreation(BarChart([1,2,3],width=1.5,height=2,color="#000000").move_to([-2.5,2,0])),run_time=2)
        self.play(ShowCreation(BarChart([1,2,3],width=3,height=1,color="#008800").move_to([4.5,0,0])),run_time=2)
        self.play(ShowCreation(BarChart([1,2,3],).move_to([-5,0,0]).scale(0.5)),run_time=2)
