Hi everyone,

Please, see the attached image.

Is there any setting in ELK, that could make the connection in the red rectangle shorter? We have many of this kind connections in our graph.

Thanks for your help!

Dear all,

A post above was my first in eclipse forum. I was so exited about it so I forgot my manners Smile

The ELK version: 0.1.0.201512040302
We are using Graphiti: 0.12.1.v20150916-0905

We have to make changes to ELK - Graphiti integration. The only change:
@Override
protected KNode createNode(final LayoutMapping<PictogramElement> mapping, final KNode parentNode, final Shape shape) {

final KNode node = super.createNode(mapping, parentNode, shape);
final KShapeLayout nodeLayout = node.getData(KShapeLayout.class);
nodeLayout.setProperty(LayoutOptions.DIRECTION, Direction.DOWN);
nodeLayout.setProperty(LayoutOptions.LAYOUT_HIERARCHY, true);

return node;
}
The rest of the configuration (layout algorithm etc) is default.
Hopefully, this time all information is available.

Thanks!

Hi,

sorry for the late reply. Try changing the node placement algorithm on all parent nodes by setting the following property:

parentNode.setProperty(Properties.NODE_PLACER, NodePlacementStrategy.BRANDES_KOEPF);

Check if that helps.
