title: Error with Chart.js : TypeError: t is undefined
body: <p>I keep getting this error and I wasn't able to display a Chart.js chart yet, although I have tried multiples codes I found on the internet.</p>
  
  <p>Here is the relevant part of the HTML :</p>
  
  <pre><code>&lt;head&gt;
      &lt;script src = "https://cdnjs.cloudflare.com/ajax/libs/Chart.js/1.0.2/Chart.min.js"&gt;&lt;/script&gt;
      ...
  &lt;/head&gt;
  
  &lt;body&gt;
      &lt;canvas id = "myChart"&gt;&lt;/canvas&gt;
      ...
  &lt;/body&gt;
  </code></pre>
  
  <p>Here is the javascript : </p>
  
  <pre><code>var ctx = document.getElementById("myChart");
  var myChart = new Chart(ctx, {
      type: 'bar',
      data: {
          labels: ["Red", "Blue", "Yellow", "Green", "Purple", "Orange"],
          datasets: [{
              label: '# of Votes',
              data: [12, 19, 3, 5, 2, 3],
              backgroundColor: [
                  'rgba(255, 99, 132, 0.2)',
                  'rgba(54, 162, 235, 0.2)',
                  'rgba(255, 206, 86, 0.2)',
                  'rgba(75, 192, 192, 0.2)',
                  'rgba(153, 102, 255, 0.2)',
                  'rgba(255, 159, 64, 0.2)'
              ],
              borderColor: [
                  'rgba(255,99,132,1)',
                  'rgba(54, 162, 235, 1)',
                  'rgba(255, 206, 86, 1)',
                  'rgba(75, 192, 192, 1)',
                  'rgba(153, 102, 255, 1)',
                  'rgba(255, 159, 64, 1)'
              ],
              borderWidth: 1
          }]
      },
      options: {
          scales: {
              yAxes: [{
                  ticks: {
                      beginAtZero:true
                  }
              }]
          }
      }
  });
  </code></pre>
  
  <p>I found that example here : <a href="http://www.chartjs.org/docs/" rel="noreferrer">http://www.chartjs.org/docs/</a></p>
  
  <p>And I get this error in the console :</p>
  
  <pre><code>TypeError: t is undefined
