title: Chart.js doughnut chart tooltip size?
body: <p>i'm want to resize tooltips on chart.
  I've used global settings but doesn't work. Tooltips on my charts are too small.

  <pre><code>$(document).ready(function () {
      // Chart options
      Chart.defaults.global.legend.display = false;
      Chart.defaults.global.titleFontSize = 20;
      var ctx = document.getElementById("Chart1");
      var myChart = new Chart(ctx, {
          type: 'doughnut',
          data: {
              labels: [
                  "Produkty",
                  ""
              ],
              datasets: [
              {
                  data: &lt;?=json_encode(array_values($values));?&gt;,
                  backgroundColor: [
                      "#2ecc71",
                      "#3498db"
                  ],
                  hoverBackgroundColor: [
                      "#27ae60",
                      "#2980b9"
                  ]

          },
          options: {
              cutoutPercentage: 80
          }
      });
  });
