title: How to add the value with Gauge.js
body: <p>I'm actually working with gauge.js. It's working correctly but I would like to add the value just as legend at the bottom of the canvas. In my example I just want to display 41%.
  Do you know a way to achieve this part ?</p>
  
  <p>Here is the jsfiddle : <a href="http://jsfiddle.net/mopaetxp/" rel="nofollow">http://jsfiddle.net/mopaetxp/</a></p>
  
  <pre><code>&lt;canvas id="foo"&gt;&lt;/canvas&gt;
  
  var opts = {
  lines: 12, // The number of lines to draw
  angle: 0, // The length of each line
  lineWidth: 0.1, // The line thickness
  pointer: {
  length: 0.9, // The radius of the inner circle
  strokeWidth: 0.035, // The rotation offset
  color: '#000000' // Fill color
  },
  limitMax: 'false',   // If true, the pointer will not go past the end of the gauge
  colorStart: '#006EAB',   // Colors
  colorStop: '#006EAB',    // just experiment with them
  strokeColor: '#FFFFFF',   // to see which ones work best for you
  generateGradient: true
  };
  var target = document.getElementById('foo'); // your canvas element
  var gauge = new Donut(target).setOptions(opts); // create sexy gauge!
  gauge.maxValue = 100; // set max gauge value
  gauge.animationSpeed = 10; // set animation speed (32 is default value)
  gauge.set(41); // set actual value
  </code></pre>
  
  <p>Thanks a lot.</p>
