piePeripheralLabeler(n) piePeripheralLabeler class piePeripheralLabeler(n)______________________________________________________________________________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 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
%".
