Change the color of a node by graphml file

[BELLAFKIH hayat]

Hello,

 I am using cytoscape to visualize a graph by using the graphml format. i like to change the style of only one node. I find this example:

<?xml version="1.0" encoding="UTF-8"?>

<graphml xmlns="http://graphml.graphdrawing.org/xmlns"  

      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

      xsi:schemaLocation="http://graphml.graphdrawing.org/xmlns 

        http://graphml.graphdrawing.org/xmlns/1.0/graphml.xsd">

  <key id="d0" for="node" attr.name="color" attr.type="string">

    <default>yellow</default>

  </key>

  <key id="d1" for="edge" attr.name="weight" attr.type="double"/>

  <graph id="G" edgedefault="undirected">

    <node id="n0">

      <data key="d0">green</data>

    </node>

    <node id="n1"/>

    <node id="n2">

      <data key="d0">blue</data>

    </node>

    <node id="n3">

      <data key="d0">red</data>

    </node>

    <node id="n4"/>

    <node id="n5">

      <data key="d0">turquoise</data>

    </node>

    <edge id="e0" source="n0" target="n2">

      <data key="d1">1.0</data>

    </edge>

    <edge id="e1" source="n0" target="n1">

      <data key="d1">1.0</data>

    </edge>

    <edge id="e2" source="n1" target="n3">

      <data key="d1">2.0</data>

    </edge>

    <edge id="e3" source="n3" target="n2"/>

    <edge id="e4" source="n2" target="n4"/>

    <edge id="e5" source="n3" target="n5"/>

    <edge id="e6" source="n5" target="n4">

      <data key="d1">1.1</data>

    </edge>

  </graph>

</graphml>

but when i import the file in cytoscape, the color of nodes was overrided by the default style. 

thanks in advance.

Hi,
   Sure -- all you're doing is importing a new column called "color".  There isn't anything magic about a column named color (it could be called "MyLook" or whatever).  Once you've imported your file, just go to the Style panel and set the Fill Color to be a passthrough mapping from your column.   As long as Cytoscape understands the Color names, it will "just work".
