docstr: Sets the line back off from the end point of the nth line
  segment (in px). This option is useful e.g. to avoid overlap
  with arrowhead markers. With "auto" the lines would trim before
  markers if `marker.angleref` is set to "previous".
  
  The 'backoff' property is a number and may be specified as:
    - An int or float in the interval [0, inf]
    - A tuple, list, or one-dimensional numpy array of the above
  
  Returns
  -------
  int|float|numpy.ndarray
