Hello,

I'm using spring layout, when arranging using the method Layout.Arrange(Diagram) everything works as expected.

However when the method Layout.Arrange(Diagram, DiagramItemCollection) is used with a set of diagram items to be arranged, the results are wrongly different. The items are not laid out as expected.

Sample follows.
[code]
SpringLayout layout = new SpringLayout();
layout.IterationCount = 1000;
layout.EnableClusters = true;
layout.MinimizeCrossings = true;
layout.MultipleGraphsPlacement = MultipleGraphsPlacement.Vertical;
layout.NodeDistance = 50f;

// works
layout.Arrange(Diagram);

// this doesn't work
//layout.Arrange(Diagram, diagramItems);
[/code]

Thanks!

Thanks for replying and for the tip to keep nodes at their initial positions when laying out with the spring layout.

Yes, I tried to add the diagram links to the collection as well. Unfortunately with the sane effect.
