First step

Link to prototye.js and to jsxgraphcore.js: 

<link rel="stylesheet" type="text/css" href="http://jsxgraph.uni-bayreuth.de/distrib/jsxgraph.css" />
<script type="text/javascript" src="http://jsxgraph.uni-bayreuth.de/distrib/jsxgraphcore.js"></script>

Second step

Insert a div inside of the document body: 

<div id="box" class="jxgbox" style="width:400px; height:400px;"></div>

Third step

Connect JXG with the div (usually at the end of the document body) and call initBoard(): 

<script type="text/javascript">
 var board = JXG.JSXGraph.initBoard('box', {boundingbox: [-2, 4, 6, -4], axis:true, grid:true});
</script>
  • Parameter 1: id of the div tag
  • Parameter 2: properties of the board.

Possible properties of the board

  • originX, originY (in pixel)
  • unitX, unitY (in pixel)
  • zoomX, zoomY
  • Or easier than origin*, unit* and zoom*: Bounding box
  • axis (true/false)
  • grid (true/false)
  • showNavigation (true/false)
  • showCopyright (true/false)

More than one boards can be initialised simultaneously in one HTML file.

The result

The complete code

<script type="text/javascript" src="http://jsxgraph.uni-bayreuth.de/distrib/jsxgraphcore.js"></script>
</head>
<body>
<div id="box" class="jxgbox" style="width:400px; height:400px;"></div>
<script type="text/javascript">
 var board = JXG.JSXGraph.initBoard('box', {boundingbox: [-2, 4, 6, -4], axis:true, grid:true});
</script>
