iReport4.6.0图表操作
做报表，图表肯定是少不了的，虽然是疲惫的周一工作还是要做
做报表，图表肯定是少不了的，虽然是疲惫的周一工作还是要做啊、、、
第一步：创建一个新的空白项目，数据源创建这个网上很多资料，不是本章重点就不再详述
第二步：iReport界面，窗口->组件面板调出来，里面有一个Chart组件，直接将其拖动到新建的报表中，接下里会弹出
我们选择第一个，做一个pie chart，点击确定之后会有设置向导跟着向导一步一步来。喎?http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcD4KPHA+PC9wPgo8cD60tL2oz/K1vLfWzqrI/bK9IKO6PC9wPgoKCtGh1PG78tDCvajK/b7d1LQKCsXk1sNLZXlzus1WYWx1ZXMKCs3qs8kKCjxwPjxpbWcgc3JjPQ=="http://www.2cto.com/uploadfile/Collfiles/20140901/2014090109514933.png" alt="\">
选择数据源：
在这里面，如果你英文比较好的话应该很容易就看得出来，第一个是为每一片制定一个唯一的标志，如果有重复的，那么使用lable+id
第二个是values就是说每一块所占的大小，就是具体值，点击下一步，完成创建
在设计界面看到的效果，
点击预览可以看到：我们做的标示和内容，这样的效果不太好，那么回到设计界面，在pie chart右键，选择chart data进行修改
如下图Key、Value和label这个之前已经说过了，只要在上面进行微调就可以了，做成你需要的样子
在我做的过程中，发现label定义之后在有些图表中是没有效果的或者它会使用默认的label+key而不是你定义的值，这个有待研究
