I have seen this type of request the last years alot.
I never implemented it but you may like to try ...

People often forget that gnuplot can be used in a pipe. So you can write your programm
using pipe() and some defaults hardcoded in your programm. The result will be shown in a window controled by gnuplot.
If you need access to the window, you may try to open a shared memory (no idea if that can be done with GTK).

maybe that help some what

Betreff: [Gnuplot-info] Graphing with GNUPlot with GTK4 UI Library

Hi All,

This is my first time posting here, so my apologies if this has already
been discussed.

I was wondering if anyone has used the graphing/plotting abilities of
GNUPlot with the GTK4 UI library. In particular, I am writing my program in
C.

My first approach is going to be attempting to read in data in gnuplot from
the standard input (stdin), since I believe that is how data is being
re-directed to gnuplot in this example of live-plotting with GNUPlot:

Let me know if there are cleaner methods anyone knows of.

Thank you,
MonkeyMan
