[Gnuplot-info] decimalsign and postscript output

[S <ste...@gm...>]

Hello,
I ran over the following problem:

I have input Data which is stored with "," as decimalsign. For the
X11-terminal, plotting with
set decimalsign locale "de_DE@euro"
works, however, if I try to plot into a postscript file, it doesn't.

So far I use sed to replace the "," by "." , I would like to solve this
from within gnuplot.

Any idea, what is going wrong, here?
Thanks,

Stephan

My Minimal script shows the plot of file.txt first in x11 then in
postcript, which reveals an empty ps-file.

################script###########
set decimalsign "de_DE@euro"
set term x11
plot "file.txt"

pause -1
set term postscript eps
set out "file.ps"
replot

############data file ##########
file.txt:
1	0,1
2	0,2
3	0,3
4	0,4
5	0,5

Why not just

	set decimalsign ','

?

How does it not work?

That the file appears empty is probably unrelated to the decimalsign 
issue.  You forgot to close the output file (unset output).

And what version of gnuplot is that, anyway?

Hello,

Sorry, I should have mentioned that:

 Version 4.2 patchlevel 0
        last modified March 2007
        System: Linux 2.6.22-14-generic
(from ubuntu 7.10 repositories)

I tried this first, but gnuplot still truncated the values.
If I type
  set decimalsign ","
  show decimalsign
the output is
  decimalsign for input is  .
  decimalsign for output is ,
so i figured, that the decimalsign change is intended for graphical
output rather than input from files.
  set decimalsign locale "de_DE@euro"
  show decimalsign
outputs
  decimalsign for input is  ,
  decimalsign for output is ,
which is what I am looking for.


> How does it not work?
A postscript file is produced, its size is similar to the files with
truncated values (in my case ~17k). However, latex, gimp and kghostview
show just an empty page an no diagram.

See my new minimal script and datafile below, it produces three
.ps-files and displays one x11 window.

Without a clue,

Stephan

############script.gp###########
set term postscript eps

#first file: truncated values, since decimalsign ist "." by default
set out "truncated.ps"
plot "file.txt" w lp

#second file: still truncated values, despite "set decimalsign ","
set decimalsign ","
show decimalsign

set out "still_truncated.ps"
replot

#third file and x11: now file is read correctly (see x11 output) but
postscript output is unreadable
set decimalsign locale "de_DE@euro"
show decimalsign

set out "works_only_in_x11.ps"
replot

unset out
set term x11
replot
pause -1

Hello,

is there nobody who can help me with my problem?

I attach two files to this e-mail, which are output from the script from
my last e-mail. They are supposed to show the same graph, just that the
second one (works_only_in_x11.ps") doesn't show anything. The x11 replot
(_after_ "unset out") shows the correct graph.

Does the script from my last e-mail work with anyone elses version of
gnuplot with correct output? (mine is Version 4.2 patchlevel 0
last modified March 2007 System: Linux 2.6.22-14-generic from ubuntu
repositories)


Thanks,

Stephan

P.S.: again, the minimal script and a sample file.txt for trying out

############script.gp###########
set term postscript eps

#first file: truncated values, since decimalsign ist "." by default
set out "truncated.ps"
plot "file.txt" w lp

#second file: still truncated values, despite "set decimalsign ","
set decimalsign ","
show decimalsign

set out "still_truncated.ps"
replot

#third file and x11: now file is read correctly (see x11 output)
#but postscript output is unreadable
set decimalsign locale "de_DE@euro"
show decimalsign

set out "works_only_in_x11.ps"
replot

unset out
set term x11
replot
pause -1

version 4.2.0 has a problem with
set decimalsign locale "de_DE@euro"
when producing postscript: it writes some (not all)
float values in the postscript code with ',' instead of '.'
which confuses the postscript interpreter.

version 4.3 cvs doesn't have this problem anymore.
(version 4.2.3 has it)

I will have to live with this or switch to 4.3 cvs

Thanks for the answer, Thomas.
