Re: [cytoscape-helpdesk] explicitly set coordinates for nodes programmatically

[Scooter Morris]

Hi Michael,
    Actually, in Cytoscape 2.x this is pretty easy.   I'm going to assume that you're updating the position of a node in the current network.  If so, here is what you would do:

    public void updateNode(CyNode node, double x, double y) {
        CyNetworkView networkView = Cytoscape.getCurrentNetworkView();
        NodeView nv = networkView.getNodeView(node);
        nv.setXPosition(x);
        nv.setYPosition(y);
    }

Hope this helps!

I am new to cytoscape but want to be able to explicitly set node coordiantes. In the API documentation I have seen the CyNodeView method getXPosition() at This Location,and the corresponding set method for x and y.

 

I imagine these could be used for what I want, but am new enough to Java and the Cytoscape API that I don't understant how to invoke these methods. I don't see an example in the developer's Cookbook either. Could a simple example of their use be provided?

 

Thank you very much.
