Hi Eric,
I don't believe anyone has yet extended org-plot to support multiple
independent variable columns. Since stating work on Org-babel [1], I
know use gnuplot source-code blocks for all of my plotting needs, as
they provide a more direct interface into gnuplot. For example the
following should provide the functionality your are looking for...
#+tblname: my-table
| 1 | 2 | 1.5 | 3 |
| 2 | 4 | 3 | 9 |
| ... | | | |
#+begin_src gnuplot :var data=my-table
plot data using 1:2, data using 3:4
#+end_src
Cheers -- Eric
