Not sure whether this is a suitable place to discuss it here, maybe I need to open issues on [ogpf](https://github.com/kookma/ogpf) and [pyplot-fortran](https://github.com/jacobwilliams/pyplot-fortran), but I still decided to discuss here.

Write a large array using the `unformatted` function in Fortran is pretty comfy, and if both oo plotting bindings can write the data into the binary and allow either python or Gnuplot to read the binary file, then it would be better for people who want to do more editing in either python or Gnuplot, since their editor will not crash by the data that is stored in the code.

Just some thought on the program design, and any idea is welcome!
