NAME

piePeripheralLabeler - tkpiechart pie peripheral style labeler class

SYNOPSIS

stooop::new piePeripheralLabeler canvas ?options?

 

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
    %".
