Hi,

LayeredLayout assigns layers according to link direction. If node 3 has only outgoing links, it should be placed on first layer.

Is  there any other layout  which will be helpful this kind of requirement. Or what should i do achieve this kind of functionality.

As this not the hard and fast rule for me that node 3 is having only out-going links only.

If you just need to arrange nodes in a row disregarding their links, you could loop over them in the order you need and set their Bounds calculated from current counter value. Something like -

Code
Select All
for (var i = 0; i < ...)
    nodes[i].setBounds(new Rect(i * 60, 20, 40, 30));
