I cannot find how to make 1234567 to 1 234 567. Found only:

set decimalsign locale "fr_FR.utf8"

set format y "%'.0f"

But it shows nonsense:

result

1

set decimalsign locale "fr_FR.utf8"

set format y "%'.0f"

  • Welcome to StackOverflow! I assume you are working under Linux? Have you checked this? https://stackoverflow.com/q/22328334/7295599 I cannot test, but I would try `set decimalsign locale "french"` and `set format y "%' 0f"` – theozh Mar 05 '23 at 11:13
  • Y, I tried: gnuplot> set decimalsign locale "french" ^ line 0: Could not find requested locale – Pragmas Mar 05 '23 at 16:10

The gnuplot commands you show should work, and in fact they do work correctly on my setup. I suspect that the problem is not gnuplot per se, but the output device you are viewing the plot on. The garbage-looking sequence â Ż is likely a failure to handle the UTF-8 byte sequence representing unicode U+2006 "SIX-PER-EM SPACE" a.k.a "THIN SPACE". So my guess is that your gnuplot script is correct but something else in your environment needs to be set to UTF-8.

It might help to tell gnuplot set encoding utf8, but from the output you show I think gnuplot is already producing utf8 that isn't handled correctly afterwards.

gnuplot> set decimalsign locale "fr_FR.utf8"
         decimal_sign in locale is ,
gnuplot> set format y "%'.0f"
gnuplot> set xrange [1.e8:1.e9]
gnuplot> set tics scale 0
gnuplot> set term dumb
gnuplot> plot x

  • Well, this is strange. When I try it in Gnulot command line, it looks nice. But in bash script nope. Locale is: $ locale LANG=en_US.UTF-8 LANGUAGE= LC_CTYPE="en_US.UTF-8" LC_NUMERIC="en_US.UTF-8" LC_TIME="en_US.UTF-8" LC_COLLATE="en_US.UTF-8" LC_MONETARY="en_US.UTF-8" LC_MESSAGES="en_US.UTF-8" LC_PAPER="en_US.UTF-8" LC_NAME="en_US.UTF-8" LC_ADDRESS="en_US.UTF-8" LC_TELEPHONE="en_US.UTF-8" LC_MEASUREMENT="en_US.UTF-8" LC_IDENTIFICATION="en_US.UTF-8" LC_ALL= So I don't understand. – Pragmas Mar 05 '23 at 19:14
