Hi,

Is there any way the avoid link overlapping  issue when we use Layered Layout.
Crossing the links are fine. But in some cases two links gets overlapped and its not easy to recognize the links.

Thanks
Kiran B

Hi,

Links overlap after LayeredLayout if they connect the same pair of nodes. You could pull them apart by offsetting their control points after calling layout.arrange:

Code
Select All
var Utils = MindFusion.Diagramming.Utils;

for (var i1 = 0; i1 < diagram.links.length; i1++)
{
	var l1 = diagram.links[i1];
	for (var i2 = i1 + 1; i2 < diagram.links.length; i2++)
	{
		var l2 = diagram.links[i2];

		if (l1.getOrigin() == l2.getOrigin() &&
			l1.getDestination() == l2.getDestination())
		{
			Utils.offsetPointCollection(l1.points, l1.points, { x: -1, y: 0 });
			Utils.offsetPointCollection(l2.points, l2.points, { x: +1, y: 0 });
			l1.updateFromPoints();
			l2.updateFromPoints();
		}
	}
}


I hope that helps,
Stoyan
