Element Detail
Legend
This element has no direct constructor. To create an instance of this element you have to call JXG.Board#create with type "legend".

Possible parent array combinations are:
{Number} x

Horizontal coordinate of the left top point of the legend


{Number} y

Vertical coordinate of the left top point of the legend


Throws:
{Exception}
If the element cannot be constructed with the given parent objects an exception is thrown.
Examples:
var board = JXG.JSXGraph.initBoard('jxgbox', {axis:true,boundingbox:[-4,48.3,12.0,-2.3]});
var x       = [-3,-2,-1,0,1,2,3,4,5,6,7,8];
var dataArr = [4,7,7,27,33,37,46,22,11,4,1,0];

colors = ['green', 'yellow', 'red', 'blue'];
board.create('chart', [x,dataArr], {chartStyle:'bar', width:1.0, labels:dataArr, colors: colors} );
board.create('legend', [8, 45], {labels:dataArr, colors: colors, strokeWidth:5} );
