Inject custom x and y coordinates for each term into chart.

        Parameters
        ----------
        x_coords: array-like
            positions on x-axis \in [0,1]
        y_coords: array-like
            positions on y-axis \in [0,1]
        rescale_x: lambda list[0,1]: list[0,1], default identity
            Rescales x-axis after filtering
        rescale_y: lambda list[0,1]: list[0,1], default identity
            Rescales y-axis after filtering
        original_x : array-like, optional
            Original, unscaled x-values.  Defaults to x_coords
        original_y : array-like, optional
            Original, unscaled y-values.  Defaults to y_coords
        Returns
        -------
