docstr: Sets the image container size vertically. The image will be
  sized based on the `position` value. When `yref` is set to
  `paper`, units are sized relative to the plot height. When
  `yref` ends with ` domain`, units are sized relative to the
  axis height.
  
  The 'sizey' property is a number and may be specified as:
    - An int or float
  
  Returns
