Including JSXGraph into HTML

For including JSXGraph into HTML, two files are necessary:

You can either download these three files and use the local copy or you can use the online version.

Usage of a local copy

If you want to include a local copy of JSXGraph in your HTML file then you have to write the following lines into the document head: 

<head>
 <link rel="stylesheet" type="text/css" href="jsxgraph.css" />
 <script type="text/javascript" src="jsxgraphcore.js"></script>
</head>

Usage of the online copy

If you want to include the online of JSXGraph in your HTML file then you have to write the following lines into the document head: 

<head>
 <link rel="stylesheet" type="text/css" href="https://jsxgraph.org/distrib/jsxgraph.css" />
 <script type="text/javascript" src="https://jsxgraph.org/distrib/jsxgraphcore.js"></script>
</head>

Include a drawing panel into the HTML

The geometric construction which is displayed by JSXGraph resides in an HTML element. Usually, a div-element is taken. This division needs an ID. Using this ID, we declare this element to be a drawing panel of JSXGraph.

The following code has to be placed into the body part of an HTML file: 

<div id="box" class="jxgbox" style="width:500px; height:500px;"></div>
<script type="text/javascript">
 var board = JXG.JSXGraph.initBoard('box', {boundingbox: [-5, 5, 5, -5]});
</script>

We can use as many different drawing panels as we like in one HTML file.

Example

<link rel="stylesheet" type="text/css" href="https://jsxgraph.org/distrib/jsxgraph.css" />
<script type="text/javascript" src="https://jsxgraph.org/distrib/jsxgraphcore.js"></script>
<div id="jxgbox" class="jxgbox" style="width:500px; height:500px;"></div>
<script language="JavaScript"> 			
 board = JXG.JSXGraph.initBoard('jxgbox', {boundingbox: [-5, 5, 5, -5]});
 g1 = board.create('point', [1, -1], {style:6});
 g2 = board.create('point', [2.5, -2], {style:6});
 g3 = board.create('point', [1, -3], {style:5});
 g4 = board.create('point', [2.5, -4], {style:5});
 g5 = board.create('point', [-4, 1], {style:5, name:''});

 c1 = board.create('curve', [
       function(t){ return (g1.X()-g2.X())*Math.cos(t)+g3.X()*Math.cos(t*(g1.X()-g2.X())/g2.X()); },
       function(t){ return (g1.X()-g2.X())*Math.sin(t)+g3.X()*Math.sin(t*(g1.X()-g2.X())/g2.X()); },
       0,function(){ return Math.PI*7*Math.abs(g4.X());}],{
          strokeWidth: function() { return g5.Y()*3; },
          strokeOpacity: function() { return g5.Y()*0.6; }
         });
</script>
