title: Get Value Data Hidden On C3js
body: <p>I'am using chart plugins from c3js.org like this:</p>
  
  <pre><code>data: {
      x : 'x',
      columns: [['data1',10,20,30],['data2',40,28,10]]
      type: 'bar',
      hide: ["hide1","hide2"],
      onclick: function(d,i){
                  console.log(d);
      },
      labels: true
  },
  </code></pre>
  
  <p>Is there a way to get value from data hidden above?</p>
  
  <p>Thanks before, and sorry for bad my english.</p>
