Heard about it. Never used.

Cryptic syntax IMO.

I guess I need weeks of learning basics in order to understand GnuPlot so that
I am able to derive those plot-lines all by myself?

Then I get «Starting gnuplot plotting program...Done» in my
mini-buffer.

That's it.

I recognized that a *gnuplot* buffer was created in background. Its
content is ...

`----

... which I do not understand yet.

Since you just mentioned invoking org-plot/gnuplot, I guess there
should be any result somewhere somehow which did not work at my
side.

I could not locate any file or directory /tmp/org-plot11956t0A.

What *should* happen?
