RGraph:是基于HTML5canvas标签,采用Javascript画图的库。

优点:由于是采用js在客户端浏览器上画图,所以它能快速显示页面和减轻服务器负载。

缺点:浏览器必须支持HTML5,不能够保存图表。

本文介绍一款名叫Rgraph的插件,使用RGraph统计图制作插件的话,可以将这个资源占用减少到接近零的程度,因为所有创建统计图的工作都是在客户端完成的,就像渲染HTML网页一样,服务器端只负责发送数据,不再负责统计图的生成与发送了,同时带宽的占用情况也大大得到了改善。
另外,由于统计图是依靠JavaScript来生成的,所以当你查看这个显示统计图的HTML网页的时候,该网页是可以为离线状态的了。

How different is JavaScript charts from Flash charts?

FusionCharts XT in its JavaScript flavor essentially tries to provide a uniform visualization experience on desktop and mobile platforms by rendering FusionCharts using advanced HTML5 capabilities of devices that does not support Flash. However, due to the inherent difference between the technologies and differences in various browsers causes minor disparity between the Flash and JavaScript variants of the charts. (IOS can't support flash)
