docstr: Sets how many points it takes to create a cluster or advance to
  the next cluster step. Use this in conjunction with arrays for
  `size` and / or `color`. If an integer, steps start at
  multiples of this number. If an array, each step extends from
  the given value until one less than the next value.
  
  The 'step' property is a number and may be specified as:
    - An int or float in the interval [-1, inf]
    - A tuple, list, or one-dimensional numpy array of the above
  
  Returns
  -------
  int|float|numpy.ndarray
