Bundle_parallel_edges problem

[lcastri]

Hi,

I'm encountering a strange issue with the bundle_parallel_edges parameter. I am generating the graph in the following way:

a = Graph(G, 
                    node_layout = 'dot',
                    node_size = 5,
                    node_color = 'orange',
                    node_label_fontdict = dict(size=14),
                    node_label_offset = 0.1,
                    node_alpha = 1,

                    arrows = True,
                    edge_layout = 'curved',
                    edge_label = False,
                    edge_color = 'grey', 
                    edge_width = edge_width,
                    edge_alpha = 1,
                    edge_zorder = 1,
                    edge_label_position = 0.35,
                    edge_layout_kwargs = dict(bundle_parallel_edges = True, k = 0.05))

where edge_width is defined as a dict containing different width for each edge. I get the following graph:

As you can see, there are 3 bi-directed edges: v <-> $g_r$, v <-> r, $\omega$ <-> $\theta_g$, but only the bi-directed link between $\omega$ and $\theta_g$ is in the desired format. Am I setting something incorrectly?

Wow, it fails not in one but in two different ways. That is impressive, and screwed up at the same time.

Can you paste the data and code required to generate G, and let me know what version (print(netgraph.__version__)) and/or which branch you are using?

[lcastri]

I am using the main branch version 4.13.2.

In the following a zip folder containing a json file and python script to generate the graph:

It looks like I fixed the issue some time ago, when I overhauled the edge artists and edge routing routines to support multi-graph visualisations.

However, I haven't merged the dev branch since, as I am working on the next major release (and will be for some time). Until the next major version release, I would suggest using the dev branch. You can install the dev branch with:

pip install https://github.com/paulbrodersen/netgraph/archive/dev.zip

Let me know if that fixes the issue on your end, too.

Yes, it works. Thanks :)
