title: jRange range picker set value problems
body: <p>Just wondering how to set the value on the jRange range picker.</p>
  
  <p>Following the documentation it says to do the code below, although the 2 dots seemed to be pinned in random spots.</p>
  
  <pre><code>$('.range-slider').jRange({
      from: 0,
      to: 36,
      step: 0.25,
      scale: [0, 6, 12, 6, 12, 6, 0],
      format: '%s',
      width: '100%',
      showLabels: true,
      isRange: true
  });
  $('.range-slider').jRange('setValue', '20,26');
  </code></pre>
