#4645 — Label problem

I am trying to get a ylabel like the LaTeX form $i\sqrt{\tau}$.
Without the i it's easy, '{/Symbol \326 \164}' but as soon as
introduce the i it goes haywire.
How do get that label? I am plotting into postscript enh eps.

Symbol fonts?
This is the year 2024, use utf8.

Could you expand on that? What should I do in a gnuplot
script?

set ylabel "{/:Italic {i \U+221A \U+0305\U+03C4}}"

That looks similar to the LaTex output.

Tried that, no good. I must bemissing something. Here is
a mini-example

gnuplot << eoi
set term postscript enh eps 24
set output 'mini.eps'
set xlabel "x"
#set ylabel '{/Symbol i \326 \164}' norotate  --- no good
#set ylabel '{i /Symbol \326 \164}' norotate  --- no good
set ylabel "{/:Italic {i \U+221A \U+0305\U+03C4}}"
plot x*sqrt(x) w p pt 7
quit
eoi
gv mini.eps

What am I missing?--

 Use term epscairo instead of eps. The problem is to realise the
"topline" of the square root. So it can be better only use:
set ylabel "{/:Italic {i \U+221A \U+03C4}}"

That only turns the plot on its side, but still the same
garbled y label.

Don't know what the problem on your machine is. Here, tested on WIN10
and Linux, the following looks good.
WIN and Linux with gnuplot 5.4.8

set term epscairo
set output 'mini.eps'
set xlabel "x"
set ylabel "{/:Italic {i \U+221A\U+03C4}}"
set arrow 1 from screen 0.0145,0.56 rto screen 0.0,0.025 nohead
plot x*sqrt(x) w p pt 7
set out

That doesn't work either, see the result here

Is there any way I can use LaTeX notation?

That might have been a can of worms. I found a solution
though, e.g.

set label '{/Times-Roman i}' at -1,0.28
set label '{/Symbol \326 \164}' at -0.8,0.28

with a bit of fiddling to get them in the right place.
Not elegant but it works.

Has you include the "set encoding utf8" before the set term?

set encoding utf8
set term epscairo
set output 'mini-utf8.eps'
set xlabel "x"
set ylabel "{/:Italic {i \U+221A\U+03C4}}"
set arrow 1 from screen 0.0145,0.56 rto screen 0.0,0.025 nohead
plot x*sqrt(x) w p pt 7
set out



> Is there any way I can use LaTeX notation?

Yes.

set ylabel '$i \sqrt{\tau}$'
set out 'mini-eps.tex'
set terminal cairolatex eps input
plot x*sqrt(x) w p pt 7
set out

After this you have two files in your directory.
mini-eps.tex and mini-eps.eps

you must include the .tex file in your LaTeX file.

\input{./mini-eps.tex}

you may have to set explicitly the encoding to utf:
set encoding utf8

You forgot to show _how_ you added that 'i'.

Nor is "goes haywire" a very enlightening description of the result.
