Hi Andreas, I forgot to send the following remarks in my previous
post.
I encounter a problem with pgfplots. The following works, and produces a
png with a white background
#+NAME: python-tikz
#+header: :results raw :file py2tikz_sin.png
#+header: :imagemagick yes :fit yes :headers '("\\usepackage{tikz,pgfplots}")
#+BEGIN_SRC latex :exports results
\begin{tikzpicture}
\begin{axis}
\draw [green,->] (0,0) -- (2,2) -- (3,1);
\end{axis}
\end{tikzpicture}
#+END_SRC
However, the following produces a png with only the axis displayed (but
the boundaries are wrong), the data points don't appear. Strangely, the
png produced is transparent: the background is the one of the Emacs buffer.
#+NAME: python-tikz
#+header: :results raw :file py2tikz_sin.png
#+header: :imagemagick yes :fit yes :headers '("\\usepackage{tikz,pgfplots}")
#+BEGIN_SRC latex :exports results
\begin{tikzpicture}
\begin{axis}
\addplot [red,only lines] table {sin_py2csv.csv};
\end{axis}
\end{tikzpicture}
#+END_SRC
The temp latex file seems ok (pdflatex produces a correct picture). I
couldn't find the command line for imagemagick conversion to png to test
it though.
Julien.
