Hi,

I am using ArrangeLayout.
a simple snippet is here,

LayeredLayout layeredLayout = new LayeredLayout();
                       layeredLayout.LinkType = LayeredLayoutLinkType.Straight;
                       layeredLayout.Orientation = MindFusion.Diagramming.Wpf.Layout.Orientation.Horizontal;
                       layeredLayout.KeepGroupLayout = true;
                       layeredLayout.Arrange(diagram);


Thanks,
Anshul

Well yes, this arranges consecutive layers from left to right:

layeredLayout.Orientation = MindFusion.Diagramming.Wpf.Layout.Orientation.Horizontal; 

Change it to Orientation.Vertical and layers will be arranged from top to bottom.

I hope that helps,
Stoyan

Hi Stoyan,

I have done this,its working but still I am not able to get that desired output.
In vertical orientation,I have got the same hierarchy but some nodes are not at their expected position.

Is their any other property by which arrangement pattern can differ?
plz let me know what is that "SegmentCount" and "RandomSeed" property does?

Thanks and Regards,
Anshul

LayeredLayout moves the nodes around to decrease the number of crossing links and make the links shorter. If you need a specific order of child nodes under some parent, check the code from this post:

I hope that helps,

RandomSeed is used in some force-directed layout algorithms to initialize their random number generator. SegmentCount is a property of DiagramLink that lets you change the number of links segments.

I hope that helps,
Stoyan
