class_docstr: Axis visual
  
  Parameters
  ----------
  pos : array
      Co-ordinates of start and end of the axis.
  domain : tuple
      The data values at the beginning and end of the axis, used for tick
      labels. i.e. (5, 10) means the axis starts at 5 and ends at 10. Default
      is (0, 1).
  tick_direction : array
      The tick direction to use (in document coordinates).
  scale_type : str
      The type of scale. For now only 'linear' is supported.
  axis_color : tuple
      RGBA values for the axis colour. Default is black.
  tick_color : tuple
      RGBA values for the tick colours. The colour for the major and minor
      ticks is currently fixed to be the same. Default is a dark grey.
  text_color : Color
      The color to use for drawing tick and axis labels
  minor_tick_length : float
      The length of minor ticks, in pixels
  major_tick_length : float
      The length of major ticks, in pixels
  tick_width : float
      Line width for the ticks
  tick_label_margin : float
      Margin between ticks and tick labels
  tick_font_size : float
      The font size to use for rendering tick labels.
  axis_width : float
      Line width for the axis
  axis_label : str
      Text to use for the axis label
  axis_label_margin : float
      Margin between ticks and axis labels
  axis_font_size : float
      The font size to use for rendering axis labels.
  font_size : float
      Font size for both the tick and axis labels. If this is set,
      tick_font_size and axis_font_size are ignored.
  anchors : iterable
      A 2-element iterable (tuple, list, etc.) giving the horizontal and
      vertical alignment of the tick labels. The first element should be one
      of 'left', 'center', or 'right', and the second element should be one
      of 'bottom', 'middle', or 'top'. If this is not specified, it is
      determined automatically.
