Re: Make Layout Algorithm Run Continuously

[Stefan Balev <stefan.balev AT gmail.com>]

Hello,

Just a complement to Guilhelm's answer:

An alternative way to do do the same thing is to use attributes:

graph.addAttribute("layout.stabilization-limit", 0.0);

graph.display();

There are several graph, node and edge attributes that can be used to tweak the default layout algorithm. More information here: http://graphstream-project.org/api/gs-core/org/graphstream/ui/layout/springbox/BarnesHutLayout.html

Best,

Hi,

Just disable the autolayout and then enable it with your layout algorithm:
/* ================================== */

Graph graph = new MultiGraph("graph");

Viewer viewer = graph.display(false);

SpringBox layout = new SpringBox();
layout.setStabilizationLimit(

0.0);
viewer.enableAutoLayout(layout);

Generator gen = new RandomGenerator(6);
gen.addSink(graph);
gen.begin();
for (int i = 0; i < 100; i++) {
    gen.nextEvents();
}
gen.end();
/* ================================== */

Best regards.

Hi.

I have tried that, but it does not seem to work. Maybe I am still doing something wrong.

Are there some layout algorithms that don't support this setting?

Here's my code (the graph always freezes after a few seconds):

/* ================================== */
Graph graph = new MultiGraph("graph");

Viewer viewer = graph.display();
SpringBox layout = new SpringBox();
layout.setStabilizationLimit(0.0);
viewer.enableAutoLayout(layout);

Generator gen = new RandomGenerator(6);
gen.addSink(graph);
gen.begin();
for (int i = 0; i < 100; i++) {
    gen.nextEvents();
}
gen.end();
/* ================================== */

Best regards,
Jacob
