Hi all.
After some struggle, I can see inline pictures in my org file.
The problem was python execution. If I execure the code in python-mode
shell, it generates a picture.
I the code executed via C-c C-c, the output picture file is empty.
I still do not know how to solve it.
And I have encountered another problem. The 'result' image is not
exported, even if I add play with :export option.
Any recommendations how to solve those?
Thanks
Petro

Remember that when you execute the code via "C-c C-c" it is run in a
temporary file which is not in the same folder as the org file from where
it was generated from. Maybe you are reading some data from a file and
Python is not able to locate the file when run with "C-c C-c".
Put ":results output" in the header and then print the current working
directory to see what I mean. If this is the problem, use the full path to
load any data you need in the python code. Remember you can use variables
in org-babel to pass this path to python, such as ":var
datapath="some_path_or_lisp_function_to_get_the_path" in the babel header..

Hi Darlan.
Thanks for you response.
I am aware of the working folder differences and use absolute path in
my scripts.
I have found a workaround in this mailing list:
http://lists.gnu.org/archive/html/emacs-orgmode/2011-06/msg00156.html
This solves my problem with inline images in results. Have not tried
exports yet.
#+begin_src python :results output raw :exports results
import numpy, matplotlib, matplotlib.pyplot
figure = matplotlib.pyplot.figure()
axes = figure.add_subplot(111, title=u"Hello", xlabel="x", ylabel="y")
x = numpy.arange(-10, 10, 0.1)
axes.plot(x, x**2)
figure.savefig("/tmp/plot_test.png")
figure.clf()
print "["+"[/tmp/plot_test.png]]"
#+end_src
