Re: Org-babel results preamble

[Eric Schulte <schulte.eric@gmail.com>]

Hi Derek,

If you name your code block, then it should be possible to update
results without any need to replace the lines preceding the results.

For example,

#+source: disk-usage
#+begin_src sh
  df
#+end_src

#+PLOT: title:"Disk Usage" ind:6 deps:(5) type:2d with:histograms set:"yrange [0:100]"
#+results: disk-usage
