FORK

Hi,

I was rewriting and improving gnuplot_i to use it in my library. You did a great job.

Although my library is mostly LGPL-2.0-only, I'll keep that part in the public domain as respect to you and the original author, and because that way you can benefit from any improvements you find in mine.

I'm mentioning you if you have no problem with that.

That code is written in GNU17 (C17 + GNU extensions), although I don't use many GNU extensions there.

The links to the code are here:

The main library link, which you already have: https://github.com/alejandro-colomar/libalx
And the rest of the links, which might change some day, but not expected as of now:
Sources: https://github.com/alejandro-colomar/libalx/tree/master/src/extra/plot
Headers: https://github.com/alejandro-colomar/libalx/tree/master/include/libalx/extra/plot
Makefile: https://github.com/alejandro-colomar/libalx/blob/master/mk/tmp/extra/plot/Makefile

Feel free to read through the code and comment anything :)

Kind regards,

Alex.
