Axes - How to hide y-axis?

[wangjia184]

        ax = Axes(
            x_range=[-1, 1],
            y_range=[0, 20],
            x_length=3,
            y_length=2,
            axis_config={"include_tip": True,
                         "tip_width":0.1,
                         "tip_height":0.1,
                         "color" : BLACK,
                         "include_ticks":False,
                         "unit_size":0.1,
                         "tick_size":0.05,
                         "font_size":18,
                         "include_numbers":False,
                         "numbers_to_include" :[], #[0, 0.5, 1.0],
                         "line_to_number_buff":0.1,
                         "longer_tick_multiple":0.5,
                         "decimal_number_config" : { "num_decimal_places": 1}},
            x_axis_config = { "exclude_origin_tick": False },
            y_axis_config = { "include_tip": False, "color" : None },
            z_index=2
        )

Please how can I hide the y-axis in Axes? I tried {color : None}, it does not work

choosing the background color of your scene should work, but why do you want to hide the Y-axis? Would a numberline be more suited for your needs?

Discord: where can I find more resources for learning manim?
