Flowchart Layout problem

There is some layout problem with flowchart if I use flowchart layout then some nodes are not on proper place.Most of time where many links are comes on one node.

I have also tried with Orthogonal Layout .This layout gives perfect flow of flowchart but there is orientation problem with orthogonal layout.I want to give a straight direction to the flowchart.

There is attachments of both layout that i have used.

Which layout should i use that i can get diagram complete diagram as orthogonal layout and direction as flowchart layout.

FlowchartLayout expects that branch and loop structures in the flowchart are properly nested, e.g. you can't have a branch from the first decision (topmost XOR in the image) exiting into a branch of a second decision. If you can't enforce such nesting, use LayeredLayout instead to arrange arbitrary graphs.

Thanks for your reply , with LayeredLayout there is need to set setNodeDistance(),setXGap() and setYGap() methods, but when i m trying to set these methods with some values then these values are not working with all diagram.

By default, NodeDistance specifies distance between node centers for nodes in the same layer. If the diagram contains nodes of varying size, call LayeredLayout.setIgnoreNodeSize(false) and NodeDistance will specify the distance between the sides of adjacent nodes. For distance between layers, call setLayerDistance().

XGap and YGap are used for padding between unconnected subgraphs according to the MultipleGraphsPlacement property.
