/**
A line chart is a way of plotting data points on a line.

Often, it is used to show trend data, and the comparison of two data sets.

##### Example

    <chart-line data="[[data]]"></chart-line>

    ...

    this.data = {
      labels: ["January", "February", "March", "April", "May", "June", "July"],
      datasets: [
        {
          label: "My First dataset",
          backgroundColor: "rgba(220,220,220,0.2)",
          borderColor: "rgba(220,220,220,1)",
          borderWidth: 1,
          pointBackgroundColor: "rgba(220,220,220,1)",
          pointBorderColor: "#fff",
          pointHoverBackgroundColor: "#fff",
          pointHoverBorderColor: "rgba(220,220,220,1)",
          data: [65, 59, 80, 81, 56, 55, 40]
        },
        {
          label: "My Second dataset",
          backgroundColor: "rgba(151,187,205,0.2)",
          borderColor: "rgba(151,187,205,1)",
          borderWidth: 1,
          pointBackgroundColor: "rgba(151,187,205,1)",
          pointBorderColor: "#fff",
          pointHighlightFill: "#fff",
          pointHoverBorderColor: "rgba(151,187,205,1)",
          data: [28, 48, 40, 19, 86, 27, 90]
        }
      ]
    };
