Hi Ihor & the List
GnuPlot is a great software. If you feel confortable with it, continue
using it! If others are used to R or Python, that is fine too.
Orgtbl-fit may be useful if:
* - You want a pure Emacs process, without external dependencies.
* - You know that Emacs-Calc can fit your data, but you are not
familiar with it.
* - Your data is already available as an Org Mode table.
* - You don't want to write a script (just point at the target column
and type M-x orgtbl-fit, that's all).
Actually, orgtbl-fit is a bridge between Org Mode tables and Calc.
By the way, Org Mode table spreadsheet capabilities are also a bridge
with Calc.
Examples & documentation can be read here:
https://github.com/tbanel/orgtblfit/blob/main/README.org
Have fun!
