class_docstr: An axis spine -- the line noting the data area boundaries.
  
  Spines are the lines connecting the axis tick marks and noting the
  boundaries of the data area. They can be placed at arbitrary
  positions. See `~.Spine.set_position` for more information.
  
  The default position is ``('outward', 0)``.
  
  Spines are subclasses of `.Patch`, and inherit much of their behavior.
  
  Spines draw a line, a circle, or an arc depending on if
  `~.Spine.set_patch_line`, `~.Spine.set_patch_circle`, or
  `~.Spine.set_patch_arc` has been called. Line-like is the default.
  
  For examples see :ref:`spines_examples`.
