I have gnuplot-5.4.1-r2 compiled without X support.
When I try the following recipe, no plot is produced and no error is
indicated:
emacs -Q:
1. M-x calc <RET>
2. [1,2,3]
3. <SPC>
4. g f
gnuplot trail (not shown automatically upon executing the recipe)
reveals the following:

immediate help: type "help" (plot window: hit 'h')
Terminal type is now 'qt'

Terminal type is now 'unknown'
^
unknown or ambiguous terminal type; type just 'set terminal' for a list
gnuplot> gnuplot> WARNING: Plotting with an 'unknown' terminal.
No output will be generated. Please select a terminal with 'set terminal'.
gnuplot>
-----------------------------------
Setting the terminal manually to one of the supported terminal solves
the issue:
(setq calc-gnuplot-default-device "qt")
However, I expected *some* kind of indication that gnuplot actually
failed. From user perspective, the failure looked like "Plotting does
not work".
Best,
Ihor

Agree. According to
<https://www.gnu.org/software/emacs/manual/html_mono/calc.html#Graphics>
it should choose a working device, in my case the "dumb" device (non X11
system) which does produces output.
BTW, you can quickly choose a device using 'g D'.

I assume that the bug report was sent from a different Emacs, since this
one has X11 support? Can you give the `M-x report-emacs-bug' output
from the Emacs that failed? That should enable others to reproduce the
issue.

Sorry, I was not clear enough. My Emacs is compiled with X11 support,
but my Gnuplot does not have X11 support. To reproduce, you need to
compile Gnuplot without X11 support.
The following is output of "set term" command in gnuplot. x11 terminal
is not there.
Available terminal types:
cairolatex LaTeX picture environment using graphicx package and Cairo backend
canvas HTML Canvas object

Oh, I see.
Looking at the `calc-graph-plot', it guesses at the display type to use
by looking at what abilities the Emacs has:
((calc-graph-w32-p)
"qt")
((or (eq window-system 'x) (getenv "DISPLAY"))
So it's doing a "set terminal x11", which then gnuplot rejects.
For this to work correctly, I think calc would have to ask gnuplot:
> The following is output of "set term" command in gnuplot. x11 terminal
> is not there.

> cairolatex LaTeX picture environment using graphicx package and Cairo backend
> canvas HTML Canvas object
> cgm Computer Graphics Metafile
> context ConTeXt with MetaFun (for PDF documents)
> domterm DomTerm terminal emulator with embedded SVG
And then parse the output to see whether gnuplot supports our guess?
Or see what gnuplot said when we tried to change the terminal... Hm...
Let's see...
(calc-gnuplot-command "set terminal" "lala")
gnuplot>
Terminal type is now 'unknown'
^
unknown or ambiguous terminal type; type just 'set terminal' for a list
Yup, that got the expected error...
OK; I've now pushed a fix for this to Emacs 28 which seems to work in my
simulated test case. Can you update Emacs and see whether it works for
you, too?

Thanks! I cannot reproduce my recipe anymore on master. The dumb
terminal is correctly used.
However, I am not sure if your fix is going to work on gnuplot ver. <3.
calc-graph-plot has the following lines:
((>= calc-gnuplot-version 3)
"dumb")
In theory, if someone is still using such an antique gnuplot version and
also compiled it without x11 support, "dumb" terminal may not be a good
fallback. It is very unlikely though.
Best,
Ihor

Thanks for testing; I'm closing the bug report, then.

Yeah, I think so. (And it doesn't make the situation worse, at least.)
