[Gnuplot-info] New version of gnuplot broke my right labels

[Mark H. <ma...@ha...>]

I've been running gnuplot for years and it worked great.  I just
installed the newest version of stable ubuntu and gnuplot broke.  I
don't know what version my old gnuplot was but it is now 5.4
patchlevel 2.  I had Y labels on both sides.  Now my right label has
disappeared.  I haven't changed any gnuplot commands.

My gnuplot only has the ".set y2label" command, and not any other
label command.  I don't know how it worked but labels appeared on both
sides.  It's weird that I only had the right side command and now that
is the broken one.  I've tried adding  ".set ylabel".

Can someone give me an idea of how to fix this?  I'd be happy to go to
an older version like 4.6 but I couldn't find a linux installer for
4.x.  Would I have to build it?  I would hate that as I always have
problems with building,  My building-fu is lacking.

On my MacBook running High Sierra:

    gnuplot> show ver

	G N U P L O T
	Version 6.0 patchlevel 2    last modified 2024-12-19 

(I check for software updates every week; doesn't everybody?)

Yes. But the OP is using the latest Ubuntu. Be aware that Gnuplot 6 will 
not build (out of the box) on Ubuntu due to a packaging error with Qt. 
This is on the Ubuntu maintainers' todo list but Ubuntu users are likely 
to be stuck on Gnulplot 5.4 for a long time yet. By the time I reported 
the issue for Gnuplot, this packaging problem had already been on their 
radar for over a year because it had been reported as having broken some 
other (gaming?) app.

@Mark While I'm not aware `.set y2label` to be a syntax accepted by gnuplot, I
found the test script below -- without the leading period -- worked fine from
the Bash by either `gnuplot ./test.spt`, or `gnuplot-qt ./test.spt`.  The test
run gnuplot 6.0.2 as currently provided by Linux Debian 13/trixie which for
now (still) is branch testing.

If an interactive GUI isn't a requirement for you, could the installation of a
second (i.e., additional) Linux distribution equally be an option for you?  Or
one which lives in a USB thumbdrive, thanks to e.g.,
[rufus](https://rufus.ie/)?

According to Debian's tracker,[1] Ubuntu 24.10 and future 25.04 currently
package version 6.0.0.  However, repology.org[2] mentions for instance Devuan
(unstable), a Debian relative, equally set to gnuplot 6.0.2.

``` test.spt
set terminal pngcairo enhanced font 'Verdana,10'
set output "test.png"
set title "title"
set grid
set key left

set xlabel "primary abscissa [x]"

set x2tics
set link x2 via x/3.14 inverse x*3.14 
set x2label "secondary abscissa [{/Symbol p}]"
set format x2 "%.1f"

set ylabel "ordinate [y]"
set format y "%.2f"

set ytics nomirror
set y2tics
set y2label "ordinate [y/8]"
set link y2 via y/8 inverse y*8
set format y2 "%.3f"

plot sin(x)
```

`.set y2label`  was my shorthand for .set("y2label") which is
javascript.  I know nothing about any other syntax, I only use it with
js.

I am not surprised that 6.0.2 works.  I went back to 4.6 and
everything works.   The bug is apparently only in 5.x.
