Hello,

I have a question about using the layout SpringLayout, I may not be using it correctly.

Disclaimer: The images of people and related found in these sample images are not real. the phone numbers which appear are from a foriegn country and not that of any US household or business. Any similarities are coincidental.

I am developing a program which analyzes phone calls and dynamically create a graph like this one:



What I would really like is a layout like this one:



The following is the code used to create the first layout.

SpringLayout sl;
sl.CreateDispatch(_T("FlowChartPro.SpringLayout"));
sl.SetArrowAnchoring(ancReassign);
sl.SetNodeDistance(300);
sl.SetEnableClusters(TRUE);
sl.SetNumIterations(1000);
sl.SetMinimizeCrossings(TRUE);
m_FlowCtrl.ArrangeDiagram(sl);
m_FlowCtrl.FitDocToObjects(5);
 

Am I missing something? I got this code by reading the API documentation as well as follow the same code from the Demo program.

I know I am close because I can dynamically generate layouts like this one:



Thanks for your help in this matter.

Hi and thanks for the quick response.

Your suggestion is on using RadialLayout for one cluster. Since I do know the root node of each cluster hypothetically I could then apply this (RadialLayout) to each one of the clusters or would that dramatically change the way the nodes are grouped together?

As you see in the last image some of the root nodes are linked by common nodes.

Thanks for your asistance here. I will confirm that the SpringLayout is needed so the clusters can be kept separate, otherwise the graph draws all over itself. (Not very pretty)

This really helped me out. You're the best! 8)
