导入GraphML以在JGraphX中创建图形
对于我正在处理的项目，我以GraphML格式的形式获取信息（我也可以更改graphML文件）并且我想从该信息创建所需的图形，我能够得到正确的通过使用mxGraphMlCodec.decode（doc，graph）方法，使用适当的边和节点进行布局，但生成的图缺少graphML文件提供的边标签的附加信息。
我找不到任何以这种方式转换为图形的graphML文件的示例。 我刚刚按照GraphML primer中所述的graphML文件指南来创建graphML文件。
这是GraphML代码：
<?xml version="1.0" encoding="UTF-8"?>
<graphml xmlns="http://graphml.graphdrawing.org/xmlns">
<key id="d1" for="edge" attr.name="edgeData" attr.type="double"/>
<graph id="DTMC" edgedefault="directed">
<node id="0"/>
<edge source="0" target="1">
<data key="d1">0.5</data>
</edge>
<edge source="0" target="2">
<data key="d1">0.5</data>
</edge>
<node id="1"/>
<edge source="1" target="3">
<data key="d1">0.5</data>
</edge>
<edge source="1" target="4">

</edge>

<node id="11"/>
<edge source="11" target="11">
<data key="d1">1.0</data>
</edge>
<node id="12"/>
<edge source="12" target="12">
<data key="d1">1.0</data>
</edge>
</graph>
</graphml>
我只是修改JGraphX examples文件夹中的ClickHandle.java文件，以便可视化图形。

jgraphx对边缘标签使用“value”属性：
<mxCell edge="1" id="4" parent="1" style="defaultEdge" source="2" target="3" value="test label">
<mxGeometry>
...
</mxGeometry>
</mxCell>
您可以尝试添加名为“value”的地址。

下面的JUnit测试显示了如何使用apache tinkerpop转换graphml文件。
