Re: how can I display 20,000 nodes in graph

Hi,

Please post a WORKING sample of code, so I could try to see what is your problem ! This one has a lot of missing part of code so it is not runnable.

Cheers.

Hello,

Thanks for your response,

Here is my code,

Graph graph = new SingleGraph("StudentGraph");

String stylesheet = "node {"+

"shape: box;"+

" fill-color: white;"+

" size: 40px;"+

" stroke-mode: plain;"+

" stroke-color: blue;"+

" stroke-width: 1px;"+

"}”;

graph.addAttribute("ui.quality");

graph.addAttribute("ui.antialias");

graph.addAttribute("ui.stylesheet", stylesheet);

for(int i=0; i< 22300; i++){

Node currentNextStudent = graph.addNode(Integer.toString(i));

currentNextStudent.addAttribute("ui.label", Integer.toString(i));

inc = inc+45;

currentNextStudent.addAttribute("xyz", 0.0, 0.0, inc);

String edgevalue = Integer.toString(nodeiter.getStudentId()) + ": " +  Integer.toString(nextNode.getStudentId());

if(edgeList.contains(edgevalue)){

Edge e = graph.getEdge(edgevalue);

int weight = e.getAttribute("layout.weight");

weight++;

e.setAttribute(edgevalue, Integer.toString(weight));

}else{

Edge e = graph.addEdge(edgevalue, currentStudent, currentNextStudent);

e.addAttribute("weight", numberofinteractions);

edgeList.add(edgevalue);

}

}

graph.display();

}

I attached my output graph for your reference.

Thanks,

Prathyusha

Hi,

We need more informations about how you create your graph. Maybe a sample of code to reproduce your problem ?

Why do you use "layout.frozen" ? Because layout will not be computed for nodes and so no coordinate will be provided to the renderer.

Cheers.

Hello,

I created 20,000 nodes and edges for each other node but I can't see all the
nodes in the graph.

I am newbie to graphstream, I used
System.setProperty("org.graphstream.ui.renderer",
"org.graphstream.ui.j2dviewer.J2DGraphRenderer");

and also "layout.frozen" for each node, but it doesn't work.

All my nodes are forming into a circle and I am unable to see the edges.

Thanks for any help.
