- After moving the plotting `while` loop in the second edit inside `with` context manager and declaring `stop_flag` as a global variable inside `fetch_input` it worked as expected.
- Lessons learned:
- 1. Use main thread for GUI/graphs
2. `with concurrent.futures.ThreadPoolExecutor() as executor:` joins all the threads in the end. So all the code, that should be parallelized must be within context manager or used without context manager.

- 2nd snippet in question now contains working code.
