Hi

I want ti include a gantt chart into my org document by using pgfgantt.

I use the following:

#+LATEX_HEADER: \usepackage{pgfgantt}

* The gantt chart I
#+BEGIN_src LaTeX
  \begin {ganttchart} [hgrid=true, vgrid=true]{36}
    \gantttitlelist {1,...,3}{12} \\
    \gantttitlelist {1,...,12}{1} \\

    \ganttgroup {Modelling (France)}{1}{36} \\
  \end {ganttchart}
#+END_src

* The gantt chart II
#+BEGIN_LaTeX
  \begin {ganttchart} [hgrid=true, vgrid=true]{36}
    \gantttitlelist {1,...,3}{12} \\
    \gantttitlelist {1,...,12}{1} \\

    \ganttgroup {Modelling (France)}{1}{36} \\
  \end {ganttchart}
#+END_LaTeX

Gantt I  produces
 - syntax highlighting
 - not exported to pdf as gantchart
 - editing in indirect buffer (C-')
 - no preview of the LaTeX fragment via C-c C-x C-l have dvipng installed).
 - C-c c results in "org-babel-execute-src-block: No org-babel-execute function for LaTeX!"

Gantt II produces
 - no syntax highlighting
 - exported as chart to pdf
 - no editing in indirect buffer
 - no preview of the LaTeX fragment
 - C-c c results in "user-error: C-c C-c can do nothing useful at this location"

Can I have a block in which I have the following:

 - syntax highlighting
 - editing in indirect buffer
 - preview of the result
 - export to pdf as gannt chart?

Thanks,

Rainer
