Aligning text

Texts can be aligned with the attributes anchorX and anchorY. Possible values for anchorX are 'left', 'middle', and 'right'. Possible values for anchorY are 'bottom', 'middle', and 'top'.

Text can be rotated if it is declared as display: 'internal'. For SVG this means, instead of an HTML div the SVG text is taken as text node.

    var brd = JXG.JSXGraph.initBoard('jxgbox',{boundingbox: [-1,10,7,-1], axis:true, keepaspectratio:false});

    // Vertical line at x=3
    brd.create('line', [-3, 1, 0], {strokeWidth:1, dash:2});  
    brd.create('text', [3, 8, "Default"], {cssClass:'mytext'});
