Hi Erik,
So have I understood this right that you're following Eric's model and
passing an org table into a shell block whch calls python?
I.e. something like
#+begin_src sh :var tasks=tasks
echo "$tasks" | python gantt.py
#+end_src
In that case it should be exactly the same as running the python code in
a shell outside emacs. To debug this, how about capturing the data
that's going into python with
#+begin_src sh :var tasks=tasks
echo "$tasks" > input-data-for-python
#+end_src
and then outside emacs doing the equivalent of
python gantt.py < input-data-for-python
Does that reveal the same problem?

Re: [Orgmode] org-babel python/shell or gantt charts with gnuplot from within org-mode
Hi Eric,
thanks for this information, this already brings me one step further.
There is now another issue which I run into, trying to get this to
work: python lists seem to be a potential problem. In the code there
are several lists which are constructed by a
# Generate gnuplot lines
plot_lines = ['plot ' +
', \\\n\t'.join((' '.join(['-1',
'title "%s"' % t,
'with lines',
'linecolor %s %s ' %
(colorprefix, colors[t]),
'linewidth 6'])
for t in tasks))]
which cause the program to fail and not to produce any output when accessed.
I can create lists with append('a') however and use them mostly w/o problems.
Is there any know limitation somewhere in org-babel or am I running
into some other problem here?
(in principle this should just be run like in any normal shell, right?)
Again any hints appreciated
Erik
P.S. let me stress that the code works w/o problems from a normal
shell, since otherwise this sounds more like a python question
