NumberPlane#
Qualified name: manim.mobject.graphing.coordinate\_systems.NumberPlane
- class NumberPlane(x_range=(- 7.111111111111111, 7.111111111111111, 1), y_range=(- 4.0, 4.0, 1), x_length=None, y_length=None, background_line_style=None, faded_line_style=None, faded_line_ratio=1, make_smooth_after_applying_functions=True, **kwargs)[source]#
Bases:
Axes
Creates a cartesian plane with background lines.
- Parameters:
x_range (Sequence[float] | None) – The
[x_min, x_max, x_step]
values of the plane in the horizontal direction.y_range (Sequence[float] | None) – The
[y_min, y_max, y_step]
values of the plane in the vertical direction.x_length (float | None) – The width of the plane.
y_length (float | None) – The height of the plane.
background_line_style (dict[str, Any] | None) – Arguments that influence the construction of the background lines of the plane.
faded_line_style (dict[str, Any] | None) – Similar to
background_line_style
, affects the construction of the scene’s background lines.faded_line_ratio (int) – Determines the number of boxes within the background lines:
2
= 4 boxes,3
= 9 boxes.make_smooth_after_applying_functions (bool) – Currently non-functional.
kwargs (dict[str, Any]) – Additional arguments to be passed to
Axes
.
Note
If
x_length
ory_length
are not defined, they are automatically calculated such that one unit on each axis is one Manim unit long.Examples

- _get_lines()[source]#
- Generate all the lines, faded and not faded.
Two sets of lines are generated: one parallel to the X-axis, and parallel to the Y-axis.
- _get_lines_parallel_to_axis(axis_parallel_to, axis_perpendicular_to, freq, ratio_faded_lines)[source]#
Generate a set of lines parallel to an axis.
- Parameters:
axis_parallel_to (NumberLine) – The axis with which the lines will be parallel.
axis_perpendicular_to (NumberLine) – The axis with which the lines will be perpendicular.
ratio_faded_lines (int) – The ratio between the space between faded lines and the space between non-faded lines.
freq (float) – Frequency of non-faded lines (number of non-faded lines per graph unit).
- Returns:
- The first (i.e the non-faded lines parallel to axis_parallel_to) and second
(i.e the faded lines parallel to axis_parallel_to) sets of lines, respectively.
- Return type:
- _init_background_lines()[source]#
Will init all the lines of NumberPlanes (faded or not)
- Return type:
None
