我是靠谱客的博主魁梧小蚂蚁，最近开发中收集的这篇文章主要介绍使用jQuery jqPlot插件绘制柱状图，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

　　在一个项目研发过程中，需要显示账户的资金情况，为了给客户良好的体验我们采用了柱状图形展现，绘图的过程如果使用原生态脚本绘制这样比较麻烦，时间也会比较长，所以我们选择了jqPlot插件进行绘制，这样可以节省大量的时间，也能很快就能展示给用户。

　　插件官方地址：http://www.jqplot.com/

　　具体实现如下：

　　引用JS文件：

复制代码代码如下:

　　Javascript脚本：

复制代码代码如下:

         var data={param1:param1,param2:param2};//传递参数

         $("#chart1").html("");//绘图DIV
