Theres already one post on this stack exchange regarding a dog bone contour, but I'm trying to draw one that has the positive imaginary axis cut out as well as the dog bone. I really don't get how to use tikz, at all so I'm not really sure how to change the code to make it work.
Any help would be greatly appreciated.
Also this is the post regarding the other dog bone contour: post
\begin{scope}[rotate=90] <some drawing> \end{scope}as presented here. – FHZ Oct 07 '20 at 02:10
