Back in September, zwz asked about getting multiple graphs on a plot
from a table:
http://lists.gnu.org/archive/html/emacs-orgmode/2009-09/msg00354.html
There appears to be no answer to that question. I have the same need
and I was wondering if anybody has an answer to this.
Basically, given a table that looks like this:
| x | y1 | x | y2 |
| 1 | 2 | 1.5 | 3 |
| ... | | | |
I want to plot y1 versus x as one line on a plot and y2 versus x as
another line on the same plot. In gnuplot, this is straightforward:
plot ... using 1:2, '' using 3:4
but org-plot currently assumes :ind to have just one entry. I have
started to look at the code in org-plot to see how to generalise ind
to be a vector of columns but would rather avoid the work if somebody
else has already done this (and because although my elisp skills are
improving daily due to org-mode, they are still rather rudimentary
;-).
Thanks,
eric

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

Eric (& Tom as well),
This works like a charm! I should have guessed that org-babel would
be able to come to the rescue :-) Many thanks.
Being able to embed such arbitrary programming languages etc is
changing my whole workflow even more than org-mode itself did. A
typical org file of mine these days seems always to include latex,
shell commands and maxima code, and I can now add gnuplot to this set.
Interestingly, 15 years on, org-mode &co. are accomplishing what the
CMU folk wanted to do with their Andrew project, specifically their
=ez= editor.
It used to be that I hated leaving emacs to do anything; now it's
getting to the point that I hate even leaving org-mode! I wonder if I
can embed wanderlust within org-mode... ;-)
Thanks again,
eric
