Setting Attributes to nodes and edges dimensions and visualizing them

[Franktwis]

Hi,
I want to build a Graph and setting size of nodes and edge varying
after some operations.
If I create a bunch of CyNodes using the Cytoscape.getCyNode() method,
then create edges using those nodes with the
Cytoscape.getCyEdge() method. Then, call Cytoscape.createNetwork()
with the
lists of nodes and edges I just created. Once I've got the CyNodes
and
CyEdges how can I use its attributes to set their dimension and how
can I display all the net?

In particular I want to increase the dimension of a Node everytime I
add an edge to it. And everytime that there is a new relation between
node A and node B I wanna to increase size of the edge between them.
How can I do it?
thanks to all!

Hi.
You can do it by adding numerical attribute "degree" or something, and
when you add an edge to a node, just increase the number. Beside the
attribute, you need to create a Visual Style to reflect the change to
node size. This can be done by creating a continuous mapping
programatically. Every time you increase the degree attribute, you
can apply this Visual Style, then the node size will be changed
automatically.

Sorry,

I'm trying to study these classes but I can't understand how to use them. Do you have a simple example of how to do it?

And what does means "continuous mapping programatically", how can I do it?

thanks again
