NAME
       piePeripheralLabeler - tkpiechart pie peripheral style labeler class

       switched::configure piePeripheralLabelerObject ?options?

       switched::cget piePeripheralLabelerObject option

DESCRIPTION
       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.

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

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

       switched::cget piePeripheralLabelerObject option
              Returns an option value for the specified piePeripheralLabeler object.


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

       -justify value
              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.

       -offset value
              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.

       -smallfont
              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.

       -widestvaluetext
              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
