Hi everybody,

Is there a way to ignore some lines when using org-plot/gnuplot to plot a table
in Org? I have a table with some expenses, but the last two lines are the total
calculated from the previous lines. I'd like to plot only the expenses and
ignore the last two lines.

In the docs there is the option "deps" to specify which columns should be
plotted but I can't find an equivalent for lines (there is a line option but I
understand that it is used to send some extra command to gnuplot).

  Hi Darlan,
  
  Sorry about the extremely delayed reply.  I don't believe that what
  you've described is possible in the current implementation of org-plot.
  It is possible however using org-babel which supports gnuplot.
  Org-babel now allows indexing into the values of variable assignments.
  
  So for example a simple gnuplot example could graph the contents of a
  table by assigning that table to a variable
  
  #+tblname: squares
  | 1 |  1 |
  | 2 |  4 |
  | 3 |  9 |
  | 4 | 16 |
  | 5 | 25 |
  | 6 | 36 |
  
  #+begin_src gnuplot :var data=squares :results silent
    plot data using 1:2 with lines
  #+end_src
  
  with this new change it is possible to assign only part of the table to
  a variable as you've described above.  For example
  
  #+tblname: squares-with-sum
  |  1 |  1 |
  |  2 |  4 |
  |  3 |  9 |
  |  4 | 16 |
  |  5 | 25 |
  |  6 | 36 |
  |----+----|
  | 21 | 91 |
  
  #+begin_src gnuplot :var data=squares-with-sum[0:-3] :results silent
    plot data using 1:2 with lines
  #+end_src
  
  For more information on indexing see the documentation of the
  `org-babel-ref-index-list' function.
  
  Thanks for motivating this new feature -- Eric

    Don't worry about a late reply. Sometimes I need a lot of time just to read the
    E-Mails here in the list (this is one of the most active lists I have ever seen
    and a really good one to follow) and I wonder how you guys not only read it but
    also fix bugs and implement new features.
    
    Thanks for this Eric. It sure opens a lot of possibilities.
