Hi all -

I am plotting a directed graph, however the formatting is really important to get right so I can achieve the objectives in my assignment. However, I would need to format each edge individually. An edge will have certain formats if a certain condition is met.

How do I get different edge layouts in the same graph and plot it? I am not finding this anywhere on the internet. Is this possible?

All the best.

See the documentation pages to which I linked in my Answer; they show how to use highlight and property manipulation to do what you're asking.

Thank you very much Steven! Much appreciated. Just one last question: is there a way to loop through the edges? I wanted to do something like loop through the edges, and if the edge has a certain length, format that individual edge a certain way. How can this be done?

Best.

You can control some properties of the edge lines in the plot of a graph or digraph on a per-edge basis using the highlight function or by directly manipulating the properties of the GraphPlot object as the "Edge Line Width by Weight" example on this documentation page shows.
