Hello Manas, really interesting posts you have here. I myself am trying to work on numerical simulations in C++. I wanted to ask if you have any positive leads on plotting the data for graphs. I have tried some resources but have come up empty. I am working on a windows computer using VSCode. Please do let me know if you have any positive leads.

Thank you

Best Regards

These use gnu plot. But I prefer matplotlib these days.

Thank you very much for your reply. I was actually looking for some interface based plotting libraries and I can see that you are directly plotting from gnuplot bash. If possible would recommend any such libraries (gnuplot or matplotlib). I have tried some of them but I am facing problems installing and running them.

Thank you for your time.
