        var randomScalingFactor = function () { return Math.round(Math.random() * 100) };
        var lineChartData = {
            labels: ['January', 'February', 'March', 'April', 'May', 'June', 'July'],
            datasets: [
                {
                    label: "My Second dataset",
                    fillColor: "rgba(151,187,205,0.2)",
                    strokeColor: "rgba(151,187,205,1)",
                    pointColor: "rgba(151,187,205,1)",
                    pointStrokeColor: "#fff",
                    pointHighlightFill: "#fff",
                    pointHighlightStroke: "rgba(151,187,205,1)",
                    data: [randomScalingFactor(), randomScalingFactor(), randomScalingFactor(), randomScalingFactor(), randomScalingFactor(), randomScalingFactor(), randomScalingFactor()]
                }
            ]
        }

        window.onload = function () {
            var ctx = document.getElementById("canvas").getContext("2d");
            window.myLine = new Chart(ctx).Line(lineChartData, {
                responsive: true
            });
        }
    </script>
</body>
</html>

注意：数据源labels和data是数组，不能拼接成一个字符串放进去，没效果。

Chart有六种样式可供选择，效果挺好的。此外，还可以考虑用HighCharts和ECharts实现图表展示。
