birdeye 绘制拓扑关系图

birdeye概述

BirdEye是一个开源的Adobe Flex图表制作组件。用于创建多维数据分析可视化界面。

birdeye 可以绘制拓扑图，关系图，流程图，星空图，地图，饼图等等..

birdeye 项目地址：http://code.google.com/p/birdeye/

birdeye 源码下载：http://code.google.com/p/birdeye/source/checkout 需要用SVN.

birdeye Demo:http://birdeye.googlecode.com/svn/branches/ng/examples/demo/BirdEyeExplorer.html

birdeye svn源码地址：

svn checkout http://birdeye.googlecode.com/svn/trunk/ birdeye-read-only

checkout 大约几分钟的时间下载下来的源码如下

每个文件夹里面对应了一类图形. 导入的项目可能会报错,注意查看每个文件夹下的lib目录下的swc文件引入即可。

ravis 下是拓扑图

导入工程后，运行Level4.mxml

birdeyeravis 传递数据的方式也是通过xml

xml结构如下：

节点

name-就是显示名,desc-是描述,可以不显示. nodeColot -是节点颜色. nodeSize-节点大小. nodeClass-节点样式,nodeIcon-不清楚属性，

连接的关系xml

fromID toID就不用说了，edgeLabel-线上的显示名 color -线的颜色,edgeClass-线的样式

xml和SpringGraph绘制拓扑图的xml结构有点相似吧…

效果如下:

线的长度只有通过控件才能设置,我是通过修改源码来达到固定的。

birdeye 与SpringGraph的一点区别在于不会随意飘动，并且效果还不错。如果不想看到他的双击事件也可以通过修改源码实现.
