[description]
The pie box style labeler object is used as a slice label placer for a [class pie] object and is passed to the pie constructor via its [option -labeler] option (see the [class pie] class manual).
[para]The labels are arranged in 2 columns below the pie graphics. Each label text is placed to the right of a rectangle, the background color of which matches its corresponding slice. The slice share value is placed to the right of the label text, separated by a semicolon. Each label is actually a canvasLabel object (see the [class canvasLabel] class manual for further information).
[para]There is no need to delete a [class pieBoxLabeler] object as it is automatically handled by the pie class.
[list_begin definitions]
