Re: How much control do we have over the layout algorithm?

[guilhelm savin <guilhelm.savin AT gmail.com>]

Example is best than words. Just check the demo here : https://github.com/gsavin/gs-openord/blob/master/src/org/graphstream/algorithm/layout/openord/Demo.java

You just have to call the algorithm on a graph g :

Graph g = ... ;
...
g.display(false); // False is important
...
OpenOrdLayout layout = new OpenOrdLayout();
layout.init(g);
layout.compute();

Sorry, but you give further instrunctions on how to use the openord algorithm?

Hi Szabolcs,

You can get more control over the layout algorithm by building a viewer by yourself :

Graph g = ... ;

...

Viewer v = new Viewer(g, Viewer.TheadingModel.GRAPH_IN_ANOTHER_THREAD);

v.addDefaultView(true);

LinLog layout = new LinLog();

layout.configure(...);

v.enableAutoLayout(layout);

You can find two layouts in gs-core, LinLog and SpringBox. There is also an adaptation of the OpenOrd layout here : https://github.com/gsavin/gs-openord

We want to implement new layout algorithms since a long time but ...

Hello again,

I was wondering, how much control can be exercised over the automatic graph layout algorithm?

Is there any other algorithm available than the default force directed one?  Is it possible to control some parameters of the default algorithm?  From what I could get from the docs, it seems that it should be possible to implement a new layout algorithm, but there is only a single built-in one.  Is this correct?

Thanks for any help in advance,
Szabolcs
