char.js专门用来做数据统计图

<canvas id="cashback" width="930" height="460"></canvas>
<script type="text/javascript" src="__TMPL__Public/js/Chart.min.js"></script>
<script>
var lineChartData_cashback_total = {
            labels : ['1月','2月','3月','4月','5月','6月','7月','8月','9月','10月','11月','12月'],
            datasets : [
                {
                    fillColor : "rgba(220,220,220,0.5)",
                    strokeColor : "rgba(220,220,220,1)",
                    pointColor : "rgba(220,220,220,1)",
                    pointStrokeColor : "#0f0",
                    data : [50,60,70,80,90,100,100,120,90,100,100,120]
                }
            ]
            
        };
var cashback = new Chart(document.getElementById("cashback").getContext("2d")).Line(lineChartData_cashback_total);
</script>

如此就OK了，char.js还可以画其他的图，效果很好看
