NumberPlane ignoring x_axis_config and y_axis_config setting

[edowson]

Description of bug / unexpected behavior

I am trying to get the NumberPlane to display the co-ordinates in steps of 2, but the NumberPlane class ignores the x_axis_config and y_axis_config attributes inherited from the Axes base class

Expected behavior

The NumberPlane should display alternating co-ordinates.

How to reproduce the issue

Code for reproducing the problem

from manim import *
import numpy as np

class NumberPlaneExample(Scene):
    def construct(self):
        number_plane = NumberPlane(
            x_range=[-6, 6, 1],
            y_range=[-6, 6, 1],
            x_length=6,
            y_length=8,
            x_axis_config={"numbers_to_include": np.arange(-6, 6, 2)},
            y_axis_config={"numbers_to_include": np.arange(-6, 6, 2)},
        )

        number_plane.add_coordinates()

        self.add(number_plane)

The image below shows the output of the NumberPlane example:

from manim import *
import numpy as np

class NumberPlaneExample(Scene):
    def construct(self):
        number_plane = NumberPlane(
            x_range=[-6, 6, 1],
            y_range=[-6, 6, 1],
            x_length=6,
            y_length=8,
            x_axis_config={"numbers_to_include": np.arange(-6, 6, 2)},
            y_axis_config={"numbers_to_include": np.arange(-6, 6, 2)},
        )

        number_plane.add_coordinates()

        self.add(number_plane)

As you can see, the it doesn't respect the x or y axis config step in terms of 2 for the range -6 to 6.

If I use the Axis class, it works as intended.

from manim import *

class Graph2DExample(Scene):
    def construct(self):
        ax = Axes(
            x_range=[-6, 6, 1],
            y_range=[-6, 6, 1],
            x_length=6,
            y_length=6,
            x_axis_config={"numbers_to_include": np.arange(-6, 6, 2)},
            y_axis_config={"numbers_to_include": np.arange(-6, 6, 2)},
            tips=False,
        )

        labels = ax.get_axis_labels(
            x_label=Tex(r"$x$"), y_label=Tex(r"$y$")
        )

        self.add(ax, labels)

Q01: Since the NumberPlane class inherits from Axes class, why is it ignoring the x_axis_config and y_axis_config?

[uwezi]

so what is the difference between your usage of the Axes() and the NumberPlane()? In the NumberPlane case you added an unnecessary and unhelpful .add_coordinates() which will show all values.

class NumberPlaneExample(Scene):
    def construct(self):
        number_plane = NumberPlane(
            x_range=[-6, 6, 1],
            y_range=[-6, 6, 1],
            x_length=6,
            y_length=8,
            x_axis_config={"numbers_to_include": np.arange(-6, 6, 2)},
            y_axis_config={"numbers_to_include": np.arange(-6, 6, 2)},
        )

        #number_plane.add_coordinates()

        self.add(number_plane)

results in this rendering:

[edowson]

Thank you. I wasn't aware

number_plane.add_coordinates()

adds all co-ordinate values.
