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 actu-
       ally a canvasLabel object.

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

       stooop::new piePeripheralLabeler canvas ?options?
              Creates  a  piePeripheralLabeler object in the specified Tk can-
              vas. 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 allo-
              cated  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
              %".
