Hello,

I have this code block:

#+BEGIN_SRC python :exports results :results file
  import matplotlib.pyplot as plt, numpy as np
  x = np.linspace(-2, 2, 1000)
  plt.plot(x, np.exp(-np.power(4*x, 2)), label="shape-parameter=4")
  for i in range(-4, 5): plt.axvline(1/6 * i, ymax = 0.1, ls = "-.", color="r")
  plt.grid()
  plt.savefig('rbf-gaussian-4.pdf')
  return "rbf-gaussian-4.pdf"
#+END_SRC

When exporting to latex it nicely compiles into \includegraphics[width=.9\linewidth]{rbf-gaussian-4.pdf}.

Now I want to have this \includegraphics in a figure environement including a label (to reference it) and a caption.

How can do this best?

I have found:
http://emacs.stackexchange.com/questions/12150/add-caption-to-an-image-generated-by-a-code-block

but it doesn't work for me.

Thanks,
Florian

What did you write? What doesn't work?

This org mode document

#+NAME: fig:org_fig
#+BEGIN_SRC python :exports results :results file
  import matplotlib.pyplot as plt, numpy as np
  x = np.linspace(-2, 2, 1000)
  plt.plot(x, np.exp(-np.power(4*x, 2)), label="shape-parameter=4")
  for i in range(-4, 5): plt.axvline(1/6 * i, ymax = 0.1, ls = "-.", color="r")
  plt.grid()
  plt.savefig('rbf-gaussian-4.pdf')
  return "rbf-gaussian-4.pdf"
#+END_SRC
#+CAPTION: Org Fig
#+LABEL: fig:org_fig

Exports to:

\begin{document}

\maketitle
\tableofcontents

\includegraphics[width=.9\linewidth]{rbf-gaussian-4.pdf} \\
% Emacs 24.5.1 (Org mode 8.2.10)
\end{document}

Additionally, when evaluating it's changed to:

[...]
#+END_SRC

#+RESULTS: fig:org_fig
[[file:rbf-gaussian-4.pdf]]

#+CAPTION: Org Fig
#+LABEL: fig:org_fig


Splitting off the caption and label.

Best,
Florian

I don't know if it'll work for Python, but here's an example of what
works for me with Ditaa:

First, execute your Babel block in order to generate a #+RESULTS line.
Then, add CAPTION, ATTR_LATEX etc. lines before the RESULTS line.

Good luck!

This seems to work mostly, yes. Problem is, that org puts the label inside the caption:

\begin{figure}[htb]
\centering
\includegraphics[width=.9\linewidth]{rbf-gaussian-4.pdf}
\caption{\label{fig:GaussianExample}Gaussian Basis functions with vertex distances marked at $n \cdot \frac{1}{6}$.}
\end{figure}

This way the label does not work, i.e. won't be found by ref links.

#+BEGIN_SRC python :exports results :results file
  import matplotlib.pyplot as plt, numpy as np
  x = np.linspace(-2, 2, 1000)
  plt.plot(x, np.exp(-np.power(4*x, 2)), label="shape-parameter=4")
  for i in range(-4, 5): plt.axvline(1/6 * i, ymax = 0.1, ls = "-.", color="r")
  plt.grid()
  plt.savefig('rbf-gaussian-4.pdf')
  return "rbf-gaussian-4.pdf"
#+END_SRC

#+LABEL: fig:GaussianExample
#+CAPTION: Gaussian Basis functions with vertex distances marked at $n \cdot \frac{1}{6}$.
#+RESULTS:
[[file:rbf-gaussian-4.pdf]]


Using NAME instead of caption results in the same latex output.

Thanks,
Florian

Exactly. 

Also, there is no need for #+LABEL, which is an obsolete synonym for
#+NAME.

Of course, using NAME instead of CAPTION. But I just learned that CAPTION is just an obsolete alias for NAME.
