title: How do I type string in the tooltip in Chart.js?
body: <p>I would like to add the "%" symbol to the results data of the tooltip. How do we customize it?</p>
  
  <pre><code>&lt;script&gt;
      var ctx = document.getElementById('myChart').getContext('2d');
      var myChart = new Chart(ctx, {
          type: 'pie',
          data: {
              labels: ['@lang('home/main.korea')', '@lang('home/main.japan')'],
              datasets: [{
                  label: [
  
                  ],
                  data: [
                      {!! $koreaPercent !!} ,
                      {!! $japanPercent !!} ,
                  ],
                  backgroundColor: [
                      'red',
                      'blue',
                  ],
              }]
          },
          options: {
          }
      });
  
  &lt;/script&gt;
  </code></pre>
  
  <p>I think we need to transform the options in the data array.</p>
