Difference in rendereing of layeredDigraph

I recently updated my version of GoDiagram, and there seems to be a
change in the functionality of the layereddigraphs. Specifically, the
links, and their FromPorts seem to have changed.

When creating the flowchart, I set these properties:
layout.DirectionOption = GoLayoutDirection.Down
layout.AggressiveOption = GoLayoutLayeredDigraphAggressive.More
layout.LayeringOption = GoLayoutLayeredDigraphLayering.OptimalLinkLength

and when creating the individual links, I set these properties:
link.Orthogonal = True
link.AvoidsNodes = True

Do you have any suggestions as to what settings I can use to correct this linking?

Thanks for any advice you can give.

Here is a picture of how the new version is rendering:

What kind of node(s) are you using?

I have extended the GoTextNode class to create a “FlowNode” class.

But, I haven't done any coding that would affect the placement of links as they attach to nodes...at least as far as I know.

I’m not sure what the problem is, precisely, but you can get around it by doing something like:

[code] goView1.StartTransaction();
GoLayoutLayeredDigraph layout = new GoLayoutLayeredDigraph();
layout.Document = goView1.Document;
layout.DirectionOption = GoLayoutDirection.Down;
// any other initializations…

// improve routing of “backwards” links:
foreach (GoObject obj in goView1.Document) {
GoLabeledLink l = obj as GoLabeledLink; // or GoLink, if that’s what you are using
if (l != null && l.AvoidsNodes && l.FromPort.GoObject.Top > l.ToPort.GoObject.Top) l.CalculateRoute();

// optional niceties:
goView1.Document.Bounds = goView1.ComputeDocumentBounds();

This works well.


Not sure what has caused the behavior but, I am not dealing with charts that are terribly big so, this extra bit shouldn’t have too much of an affect on performance.

Thanks again.
