                    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>

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。
