I have a graph that I want to plot in a specific layout. My closest attempt is

 plot(G,'layout',,'layered','Sources',[1 6] ,'Sinks',[5 10],'direction','right','linewidth',LWidths);
...

I can force X and Y coordinates of nodes in my graph to achieve the layout I want by using:

plot(G,'layout','force','Iterations',0,'XStart',X,'YStart',Y,'linewidth',LWidths);
...

However, this method causes some edges to overlap and become indistinguishable.

Is there any way to get curved edges at this point?

You could try this:

plot(G,'Layout','layered','Sources',1:5 ,'Sinks',6:10,'linewidth',LWidths);

This will place all nodes 1 to 5 on one layer, and nodes 6 to 10 on another, with the curved lines between nodes on the same layer.

Thanks for the idea! That almost gets me where I wanted.

Now node ids are scrambled in each layer...

That's too bad, I'm afraid there's no way of choosing the order of the nodes in a layer (they are permuted to try to minimize the number of edge crossings, which is not really necessary here, of course).

You could try the circle layout, perhaps coupled with giving the two groups of nodes different colors again. That would have nodes 1 to 5 on one side of the circle, and nodes 6 to 10 on the other side.
