draw_pegasus: Overlapping Plots No Longer Render Correctly

[iamashwin99]

Description
Previously, it was possible to plot two graphs on top of each other (e.g., using dnx.draw_pegasus() sequentially) and achieve a combined visualisation. This no longer appears to work. Instead, only one of the plots might be visible, or they are not overlaid as expected, as demonstrated in the attached images.

To Reproduce
Run the code from the documentation here https://docs.dwavequantum.com/en/latest/ocean/api_ref_dnx/drawing.html#id1

I'm unable to reproduce the reported issue with the latest version of Ocean (8.4.0).

Please try after updating your local packages with pip install dwave-ocean-sdk==8.4.0.

[iamashwin99]

Ok here is a minimal colab notebook that you can rerun to reproduce the issue with dwave-ocean-sdk==8.4.0

Then perhaps the problem might be related to colab.

Can you try reproducing the issue on your machine?

[iamashwin99]

yes, I can reproduce it on my local machine too. The image under Current behaviour in the first post is from my local machine

But that's again in a jupyter notebook? Running inside vscode?

[iamashwin99]

yes correct

[randomir]

OK, I can reproduce it in jupyter/vscode. Will try to narrow down the specific conditions.

Looks like this issue is due to a new scaling method introduced in #236, and released in dwave-networkx==0.8.16.

Thanks for reporting it!
