title: Label outside arc (Pie chart) c3.js
body: <p>I want to show the label data outside the graph area using c3.js. I've not find any help from documentation. Please some one guide me to solve this.</p>
  
  <pre><code>var chart = c3.generate({
      data: {
        columns: data,
        type : 'pie'
      },
      axis: {
        x: {
          label: {
              text: 'data1 ',
              position: 'outer-middle'
          }
        },
        y: {
          label: {
              text: 'data2 ',
              position: 'outer-middle'
          }
  
        }
      },
      pie: {
        label: {
          show: true
        }
      },  
      onrendered: function() {
  
      }
  });
  </code></pre>
