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
