Hi,
Before asking my question, I would like to give few remarks
about use of gnuplot with org-babel and the reason why I
asked this question.
I tried to use it with org-plot but I was not really satisfied
as it didn't work clearly well with emacs installed on MS Windows.
Below a thread about this problem :
http://thread.gmane.org/gmane.emacs.orgmode/15036/focus=15032
Since gnuplot is available from Babel I tried to use to check
if I have less problem with MS Windows. If I used it with
session none and make a redirection to output file, it works
well for me.
Below an example the way I use it :
--8<---------------cut here---------------start------------->8---
#+begin_src gnuplot :session none :file out.png
set terminal png
set xlabel "gx";set ylabel "gy";set zlabel "gz"
set grid xtics ytics
set view 0,0
plot cos(x)
#+end_src
--8<---------------cut here---------------end--------------->8---
#+results:
[[file:out.png]]
With org-plot it was possible to give a table in entry. Org-plot
was able to write temporary file that was used by gnuplot.
I haven't seen such a wrapped function for gnuplot use with babel
and I wonder if it is possible to pass a table in gnuplot
block that will create a generic tmpfile.dat used by gnuplot ?
Is there a elisp function that could be use to create such file
that could be used afterwards ?
Something that could look like this :
--8<---------------cut here---------------start------------->8---
#+tblname: tablein
| A | B |
+--------+-------+
| 257.72 | 21.39 |
| 165.77 | 19.68 |
| 71.00 | 11.50 |
| 134.19 | 14.33 |
| 257.56 | 17.67 |
#+lob: functiontowrite(table=tablein, filename="tmpfile_tablein.txt")
--8<---------------cut here---------------end--------------->8---
An then use tmpfile_tablein.txt in gnuplot block.
--8<---------------cut here---------------start------------->8---
#+begin_src gnuplot :session none :file test.png
set terminal png
plot 'tmpfile_tablein.txt' us 1:2
#+end_src
--8<---------------cut here---------------end--------------->8---
Is there a tips that could be used to approach this way of doing ?

Sorry, please forget the last question.
I have just seen a thread related to gnuplot that answers
to this question.
