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.
