    option












The pie peripheral style labeler object is used as a slice label
    placer for a pie object and is passed to the pie constructor via its
    -labeler option (see the pie class manual).


The slice description text labels are arranged in 2 columns below
    the pie graphics, whereas the slice values are placed next to the slice and
    actually follow the slice as the pie is updated. Each description label text
    is placed to the right of a rectangle, the background color of which matches
    its corresponding slice. Each description label is actually a canvasLabel
    object.


There is no need to delete a piePeripheralLabeler object as
    it is automatically handled by the pie class.



  

  
Creates a piePeripheralLabeler object in the specified Tk canvas. The
      piePeripheralLabeler object identifier is returned (refered to as
      piePeripheralLabelerObject in this document).

  

  
Configures a piePeripheralLabeler object or returns all the options with
      their current values if no options are passed as parameters.

  

  
Returns an option value for the specified piePeripheralLabeler
    object.











  

  
Specifies a font for the slice labels. If not specified, the default font
      is system dependent.

  

  
Specifies how to justify labels within their own column. Must be one of
      left, center or right. Defaults to left. For
      example, if justification is right, all column labels right edges
      are aligned.

  

  
Specifies the distance between the pie graphics and the closest slice
      label. This value may be specified in any of the forms described in the
      canvas COORDINATES manual section.

  

  
Specifies a font for the slice values. It is usually a small font in order
      to avoid values overlapping when 2 slices are very close to each other. If
      not specified, the description label font (-font option) is
    used.

  

  
Specifies a string of maximum width for slice values (placed around the
      pie next to the slices), so that enough room is allocated for these value
      labels when the pie width and height are set. It defaults to 00.0. For
      example, it could be set to "00.00 %".










The labeler has the following specific tag (see the canvas
    manual page ITEM IDS AND TAGS section for more information):
