jfreechart 如何统计每年按月份的数据！？？
例如统计2005、2006、2007三年的数据，显示3条曲线。
数据如下:
月份 数量
2005-01 12
2005-02 0
2005-04 7
2005-10 8

月份 数量
2006-01 12
2006-02 0
2006-04 7
2006-10 8

月份 数量
2007-01 0
2007-02 0
2007-04 0
2007-10 0

to awaysrain(绝对零度)(既然选择了远方就要日夜前行)

这个东东我都看过，但运行的效果是按年统计的？！
我想要的是X轴是1-12月，Y轴是数量,然后曲线是年度的曲线！
希望高手们帮帮忙！！

呵呵,晕啊,你的脑袋咋就不转弯呢
用友相当于2005年
金蝶相当于2006年
