  <pre><code>                label: "Shop Sales",
                  fillColor : "rgba(255, 89, 114, 0.6)",
                  strokeColor : "rgba(51, 51, 51, 1)",
                  pointColor : "rgba(255, 89, 114, 1)",
                  pointStrokeColor : "#fff",
                  pointHighlightFill : "#fff",
                  pointHighlightStroke : "rgba(151,187,205,1)",
                  maintainAspectRatio: false,
  </code></pre>

  <pre><code>window.onload = function(){
      var ctx = document.getElementById("canvas").getContext("2d");
  
      window.myLine = new Chart(ctx).Line(lineChartData, {
  responsive: true, scaleFontColor: "#FF5972" }
