docstr: Vertical space between grid cells, expressed as a fraction of
  the total height available to one cell. Defaults to 0.1 for
  coupled-axes grids and 0.3 for independent grids.
  
  The 'ygap' property is a number and may be specified as:
    - An int or float in the interval [0, 1]
  
  Returns
