title: Chart.js padding canvas
body: <p>I'm using latest chart.js library to generate a line chart without scales, but there is a padding problem and top and bottom points are cut off. I couldn't see any option for padding canvas.</p>

  <p>My config is like below.</p>
  
  <pre><code>var config = {
      type: 'line',
      data: {
          labels: ["January", "February", "March", "April", "May", "June", "July"],
          datasets: [{
              label: "Sales",
              data: [10, 20, 50, 25, 60, 12, 48],
              fill: true,
              lineTension: 0.25,
              borderColor: "#558aeb",
              backgroundColor: "#558aeb"
          }]
      },
      options: {
          responsive: true,
          legend: {
              display: false
          },
          tooltips: {
              mode: 'label'
          },
          hover: {
              mode: 'dataset'
          },
          scales: {
              xAxes: [{
                  display: false
              }],
              yAxes: [{
                  display: false
              }]
          }
      }
  };
  </code></pre>
