class_docstr: Wrapper for python-ternary and matplotlib figure. Parameters for member
  functions simply pass through to ternary's functions with the same names.
  This class manages the matplotlib axes, the scale, and the boundary scale
  to ease the use of ternary plotting functions.
docstr: Sets the label on the bottom axis.
  
  Parameters
  ----------
  label: String
      The axis label
  position: 3-Tuple of floats, None
      The position of the text label
  rotation: float, 0
      The angle of rotation of the label
  offset: float,
      Used to compute the distance of the label from the axis
  kwargs:
      Any kwargs to pass through to matplotlib.
