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 %".
