Hallöchen!
I wonder what is the best way to include plots generated from Python
code into my notes. I found a way but maybe there's a better one.
What I do is
--8<---------------cut here---------------start------------->8---
#+begin_src python
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()
#+end_src
#+results:
: None
[[/tmp/plot_test.png]]
--8<---------------cut here---------------end--------------->8---
However, it is a little bit cumbersome. Is there an easier way to
define code (possibly with boilerplate), and let it be replaced with
the graphics file it produces?
Tschö,
Torsten.

Hello,
I have success with the following:
#+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
You get only the figure as a result, and not the code.
This method executes the code at each export. The alternative is to
set ":exports none" , to execute with C-c C-c and then to delete the
"+results:" line so that the result is exported.

Hi Torsten,
You could try
#+begin_src python :exports results :file /tmp/plot_test.png
...
#+end_src
Which should behave as desired.

Thank you, I think this is how I'll do it. Exporting is not so
important to me (at least, not yet).
Tschö,
Torsten.

Thanks also for your answer, however, one should write
print "[" + "[/tmp/plot_test.png]]"
or something like this in order to prevent the string literal from
being substituted by the bitmap.
Tschö,
Torsten.
