Add one label to multiple edges about graphmakie.jl HOT 3 OPEN

For something more generic you could extract the paths which represent the edges. Using those you can interpolate positions along the edges as well as the tangent of the edge. That's how we determine the elabel positions and rotations internally.

This data might be useful to calculate the position where you want to place your combined label.

using GLMakie, GraphMakie, Graphs

g = complete_graph(5)
fig, ax, p = graphplot(g)

# extract list of drawn curves for the edges
edgepaths = p.plots[1][:paths][]

# calculate position and tangent vectors along those lines where t in 0..1
t = 0.2
GraphMakie.interpolate(edgepaths[1], t)
# 2-element Point{2, Float32} with indices SOneTo(2):
#  -1.1051269
#  -0.36803403

GraphMakie.tangent(edgepaths[1], t)
# 2-element Point{2, Float32} with indices SOneTo(2):
#   0.42698735
#  -0.90425766

Your last question implies that you control the node positions manual anyway so I'd suggest to use Makie directly for this, i.e. use text!("foo", position=Point2(x, y)) to place the label wherever you want...

You could also set some labels to "" and move the remaining label using the elabel_shift, elabel_offset and elabel_rotation parameters.

Thanks, I'll have a deeper look if I can make it work with the tangents solution that you offered. In the meantime I've implemented the simple heuristic I've outlined in my initial post.
