    Parameters
    ----------
    transforms: numpy.ndarray
        transform matrices with the shape of [N, 4, 4]
        where N is the # of poses.
    is_relative: bool
        True for relative poses. default: False.
    mode: str
        x and y axis of trajectory. default: 'xz' following kitti format.
    style: str
        style of ploting, default: 'b.'
    axis: bool
        False to disable axis.

    Returns
    -------
    dst: numpy.ndarray
