Grouping objects
From JSXGraph Wiki
The underlying JavaScript code
var b1 = JXG.JSXGraph.initBoard('jxgbox', {originX: 200, originY: 150, unitX: 50, unitY: 50});
var pArr = [];
pArr[0] = b1.createElement('point',[0,0], {name:'A',style:6});
pArr[1] = b1.createElement('point',[2,1], {name:'B',style:6});
pArr[2] = b1.createElement('point',[2,2], {name:'C',style:6});
pArr[3] = b1.createElement('point',[0,1], {name:'D',style:6});
var poly = b1.createElement('polygon',pArr);
var gr = new JXG.Group(b1,'','',pArr);
The points are grouped together with the command
var gr = new JXG.Group(b1,'','',pArr);
In the next release (>0.66) this will be replaced by
var gr = b1.createElement('group',pArr);
