Hi,

This should work, as long as you have a corresponding merge node at the other side of each branching. Otherwise the layout class will fail to recognize the control flow structure.

If your graphs don’t have that kind of merge nodes, try using LayeredLayout with StraightenLongLinks enabled - it should creates similar results, but in such case you might have to implement additional handling for back links.

Hi,

Check how the JavaScript sample project creates graph nodes for the following code:

function test()
{
	switch(a)
	{
	case 1:
		test1();
		test2();
	case 2:
		test1();
		test2();
	case 3:
		for (i = 1; i < 100; ++i)
		{
			test1();
		}
	case 4:
		test1();
		test2();
	}
} 

It adds an end node / merge node for language structures such as branches and loops. If such end / merge nodes do not exist in the graph, the algorithm cannot recognize the code structure simply by following the graph links recursively. If you don't want such end nodes in your flowchart, you could add them only temporary in order to apply the layout, and remove them after that.

I hope that helps,
Stoyan
