[OS X TeX] pgf and gnuplot with TeXShop

[Amaury Adon]

HEllo
This is y first message in this list, so I ope you will apologize me  
if some points have been already treated.

I use the latest TeXShop beta and i'm trying to plot somme functions  
using pgf/tikz and gnuplot.

I've Installe Aquaterm, gnuplot 4.2.0 and all of this work like a  
charm in a terminal window.

However, when I try to make it work through TexShop, I got somme  
error messages.

In order to make it more consistent, ths is the minimal code I use  
for testing purpose

\begin{tikzpicture}[domain=0:4,x=2cm,y=2cm]
\draw[very thin,color=gray] (-0.1,-1.1) grid (3.9,3.9);
\draw[->] (-0.2,0) -- (4.2,0) node[right] {$x$};
\draw[->] (0,-1.2) -- (0,4.2) node[above] {$f(x)$};
\draw[color=red] plot[id=x] function{x} node[right] {$f(x) =x$};
\draw[color=blue] plot[id=sin] function{sin(x)} node[right] {$f(x) =  
\sin x$};
\draw[color=orange] plot[id=exp] function{0.05*exp(x)} node[right] {$f 
(x) = \frac{1}{20} \mathrm e^x$};
\end{tikzpicture}

and the error message

set terminal table; set output ""test gnuplot tikz".x.table"; set  
format "%.5f"
                                  ^
cannot open file; output not changed
"test gnuplot tikz.x.gnuplot", line 1: util.c: No such file or directory


set terminal table; set output ""test gnuplot tikz".sin.table"; set  
format "%.5f"
                                  ^
cannot open file; output not changed
"test gnuplot tikz.sin.gnuplot", line 1: util.c: No such file or  
directory


set terminal table; set output ""test gnuplot tikz".exp.table"; set  
format "%.5f"
                                  ^
cannot open file; output not changed
"test gnuplot tikz.exp.gnuplot", line 1: util.c: No such file or  
directory



Package pgf Warning: Plot data file `"test gnuplot tikz".x.table' not  
found. on
input line 191.


Package pgf Warning: Plot data file `"test gnuplot tikz".sin.table'  
not found.
on input line 192.


Package pgf Warning: Plot data file `"test gnuplot tikz".exp.table'  
not found.
on input line 193.


Obviously, I've tried to produce those missing file trough the shell  
but it only works with teh following

set table "test gnuplot tikz.sin.table"; set format "%.5f"

It seems like the command passed to gnuplot by gf are not valid and  
the test gnuplot tikz.sin.gnuplot file is not up to date.

Does someone have ever encounter such problem ?

Does anyone have a solution ?


Many thanks
Amaury
