可见支持的种类非常之多。在这里我们使用一下Radar Area Chart（雷达图）。使用方式如下：

引入必要的文件，注意jQuery的js文件要放在最前面，版本不一定是1.5.1，比这个版本高也行。实际中根据示例代码修改相应的地方就行。

            var background = {

                             { offset: 1, color: 'white'}]
            };

            $('#jqChart').jqChart({

                            majorTickMarks: { visible: true }
                        }
                      ],
                series: [
                            {
                                title : 'Series 1',
                                type: 'radarArea',
                                data: [65.62, 75.54, 60.45, 34.73, 85.42, 55.9, 63.6, 55.1, 77.2],
                                fillStyle: 'rgba(65,140,240,0.75)'
                            },
                            {
                                title: 'Series 2',
                                type: 'radarArea',
                                data: [76.45, 23.78, 86.45, 30.76, 23.79, 35.67, 89.56, 67.45, 38.98],
                                fillStyle: 'rgba(252,180,65,0.75)'
                            }
                        ]
            });
        });
    </script>

需要显示图表的地方，只需使用一个<div>即可：

 

 

<div id="jqChart" style="width: 500px; height: 300px;">
        </div>

显示结果如图所示：
