title: Why ChartJs is not working in IE
body: <p>The VueJs chart application in this example does not work in IE. Does anyone know why?</p>
  
  <p>For example, the following component does not print errors but does not run at the same time</p>
  
  <pre><code>&lt;div class="app"&gt;
      {{ message }}
    &lt;line-chart&gt;&lt;/line-chart&gt;
  &lt;/div&gt;
  
  
    Vue.component('line-chart', {
    extends: VueChartJs.Line,
    mounted () {
      this.renderChart({
        labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
        datasets: [
          {
            label: 'Data One',
            backgroundColor: '#f87979',
            data: [40, 39, 10, 40, 39, 80, 40]
          }
        ]
      }, {responsive: true, maintainAspectRatio: false})
    }
  
  })
  
  var vm = new Vue({
    el: '.app',
    data: {
      message: 'Hello World'
    }
  })
  </code></pre>
