        Parameters
        ----------
        ax : Axes
            The Axes to put the slider in.

        label : str
            Slider label.

        valmin : float
            The minimum value of the slider.

        valmax : float
            The maximum value of the slider.

        valinit : tuple of float or None, default: None
            The initial positions of the slider. If None the initial positions
            will be at the 25th and 75th percentiles of the range.

        valfmt : str or callable, default: None
            The way to format the range's minimal and maximal values. If a
            string, it must be in %-format. If a callable, it must have the
            signature ``valfmt(val: float) -> str``. If None, a
            `.ScalarFormatter` is used.
