locale.h and gnuplot

[Jakson Aquino]

Hello All!

When trying to see a boxplot I got the following
gnuplot error:

Spalte fuer Variable 1: TVHOURS

Erstelle gnuplot-Graphik ...


0 vermutliche Ausreisser gefunden

   --- Bitte mit ENTER fortfahren ... ---
gnuplot> plot [0,8:5,2][9:13]
'/home/jakson/stat_gpl.dat' with lines
                ^
         line 0: ':' or keyword 'to' expected


The problem is that, in many languages (among them:
German, French, Spanish, Italian, and Portuguese), the
decimal separator is not a "."; it's a ",". However,
the culprit is <locale.h>. With locale.h, the printf
function becomes very smart. It's good to see the
results of calculations printed with the correct
decimal separator, but, while writing a file to
gnuplot, locale.h is a problem.

Another --far less important-- side effect of locale.h
is that if we save columns in an ascii file running
Statist in a language other than English, it will not
be possible to open the file running Statist in
English. We would have, for example, 1,30000e+01
instead of 1.30000e+01. Since this side effect isn't
properly a bug of Statist, I think that it will be
enough to document it. And the solution is very
simple: use some tool to replace all "," with ".".

Is there any easy way of fixing the problem with
gnuplot?

Best,

Jakson
