JXG.CoordsElement,JXG.GeometryElement
   ↳ JXG.Text
         ↳ Label

Labels are text objects tied to other elements like points, lines and curves. Labels are handled internally by JSXGraph, only. There is NO constructor "board.create('label', ...)".

Defined in: text.js.
Extends JXG.Text.

Automatic position of label text.
 
Label offset from label anchor.
 
Possible string values for the position of a label for label anchor points are:
  • 'lft'
  • 'rt'
  • 'top'
  • 'bot'
  • 'ulft'
  • 'urt'
  • 'llft'
  • 'lrt'
This is relevant for non-points: line, circle, curve.

autoPosition
Automatic position of label text. When called first, the positioning algorithm starts at the position defined by offset. The algorithm tries to find a position with the least number of overlappings with other elements, while retaining the distance to the anchor element.
Defined in: options.js.
	var p1 = board.create('point', [-2, 1], {id: 'A'});
	var p2 = board.create('point', [-0.85, 1], {
     name: 'B', id: 'B', label:{autoPosition: true, offset:[10, 10]}
 });
	var p3 = board.create('point', [-1, 1.2], {
     name: 'C', id: 'C', label:{autoPosition: true, offset:[10, 10]}
 });
 var c = board.create('circle', [p1, p2]);
	var l = board.create('line', [p1, p2]);
