需求让实现每个模块之间的线动态流水化，用canvas肯定很复杂，所有用了比较投机的方法，css动画加js控制

    				$(".container").append($sparkLine)

    			//创建线
    			createLine(200,'red',2,2,1,20,20,30);
    			createLine(200,'white',2,2,1,20,20,90);
    		
    		</script>
    	</body>
    </html>

这只是个测试例子，用到了jq，例子中只有两条线，根据自己实际情况调用createLine方法创建线条并传入各种参数
