Re: [Orgmode] Gnuplot unevenly spaced non-numeric data plot?

Problem solved with babel. I was able to get everything I wanted by piecing together some examples from the mailing list and gnuplot examples/manual around the web.

Thanks!

Nick,

That works from gnuplot. Not sure about orgmode... I tried

#+PLOT: using:"2:3:xticlabels(1)"

which is not working. There's no "using" option mentioned on worg: http://orgmode.org/worg/org-tutorials/org-plot.php

Perhaps it's not possible?

I could try the org-babel method but there seems to be less documentation on this?

Gnuplot can certainly do it, but whether you can convince org-plot/gnuplot
to emit the right incantation, I don't know.

Try the following in gnuplot

       plot 'foo.data' using 2:3:xticlabels(1)

with the data file containing

,----
| a                                  0  10
| b                                 10  20
| c                                 11  30
| d                                 40  40
`----

HTH,
Nick
