Cancel during layout.arrange() method

Hi,

We are using the LayeredLayout.arrange() method to arrange our graphs.
Our graphs are made through a back-end program, and thus it is possible that the graph can be very large.
In that case, calling the LayeredLayout.arrange() method takes more than 3 minutes.
We use the arrange() method in this way:
        var layout = new LayeredLayout();
        layout.nodeDistance = 10;
        layout.layerDistance = 30;
        layout.direction = MindFusion.Graphs.LayoutDirection.LeftToRight;
        layout.multipleGraphsPlacement = MindFusion.Graphs.MultipleGraphsPlacement.Vertical;
        layout.siftingRounds = 4;
        diagram.arrange(layout);

In the case that the diagram.arrange() method takes too long, is there a way to fasten the arrange method?
Or can we cancel the arrange() method while executing?

Kind regards,
M.U.

Hi,

You can make it faster by setting smaller siftingRounds value. Cancelling layouts is not supported at this time. If your diagram contains multiple subgraphs not connected to each other, you could try adding them to temporary ContainerNodes, calling container.arrange(layout) and letting users cancel after each container.

Kind regards,
Slavcho
