title: Chart.js - callback after hover
body: <p>I need to have a callback after hovering a part of graph (donught). How can I do this? Theoretically, Chart.js doesn't provide callbacks, so this is a problem :)</p>
  
  <p>My current code:</p>
  
  <pre><code>var visitorsChart = [
              {
                  value: 60,
                  color:'#3e89dc'
              },
              {
                  value: 40,
                  color:'#88c600'
              }
          ]
  
          var visitorsChartOptions = {
              percentageInnerCutout: 70
          }
  
          var renderVisitorsChart = new Chart(document.getElementById("visitors-chart").getContext("2d"), {tooltips: {position: 'bottom left', background: 'rgba(255,255,255,0)', fontFamily: 'Open Sans', fontSize: '40px', fontWeight: '700', labelTemplate:'&lt;%=value%&gt;'}, border: {width:0}, showShadow: false}).Doughnut(visitorsChart, visitorsChartOptions);
  </code></pre>
