Functions

index_labels(mobject, label_height=0.15, background_stroke_width=5, background_stroke_color='#000000', **kwargs)

Returns a VGroup of Integer mobjects that shows the index of each submobject.

Useful for working with parts of complicated mobjects.

Parameters

• mobject (Mobject) – The mobject that will have its submobjects labelled.

• label_height (float) – The height of the labels, by default 0.15.

• background_stroke_width – The stroke width of the outline of the labels, by default 5.

• background_stroke_color – The stroke color of the outline of labels.

• kwargs – Additional parameters to be passed into the :class`~.Integer` mobjects used to construct the labels.

Examples

Example: IndexLabelsExample

from manim import *

class IndexLabelsExample(Scene):
    def construct(self):
        text = MathTex(
            "\\frac{d}{dx}f(x)g(x)=",
            "f(x)\\frac{d}{dx}g(x)",
            "+",
            "g(x)\\frac{d}{dx}f(x)",
        )

        #index the fist term in the MathTex mob
        indices = index_labels(text[0])

        text[0][1].set_color(PURPLE_B)
        text[0][8:12].set_color(DARK_BLUE)

        self.add(text, indices)

print_family(mobject, n_tabs=0)
