Change Layout randomly

[ghost]

Hello,
if i use e.g. the FR algorithm and then use it again by clicking a button, it changes the layout. But the algorithm is the same. So why should it change with same algorithm and same data?
Thanks:)

Same algorithm and same data but differnt layout, why?

Hello, that's because some algorithms use random initial positions to provide different layout results. You can use algorithm Seed property to specify exact seed if you want one layout result to persist through many generations.

Can you give me an example for some algorithm please?

To be correct you have to set Seed property for layout algorithm parameters like:
graphArea.LogicCore.DefaultLayoutAlgorithmParams.Seed = 20939202;
