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
