是否有可能改变甜甜圈图表工具提示的风格？

Question

目前我有这个圆环图

我正在尝试像这样改变工具提示风格

 var ctx = document.getElementById('mycanvas').getContext('2d');
   var chart = new Chart(ctx, {
      type: 'doughnut',
      data: {
         labels: ["AA", "BB", "CC", "DD", "EE"],
         datasets: [{
            label: "My First dataset",
            backgroundColor: ['yellow', 'pink', 'red', '#E8A3D7', '#CFA3FD'],
            data: [7, 3, 3, 4, 8],
         }]
      },
      options: {
         legend: {
            position: 'right',
            labels: {
               boxWidth: 12
            }
         }
      }
   });

但我找不到办法。有人知道这是否可行？
