Eric,

thanks for this suggestion as well as the one using org-babel (which I
would have typically used myself these days).  However, the point
still stands: why doesn't what Johan tried initially work?

I have narrowed down what causes the problem although I don't
understand why (I haven't had any time to look at the elisp code).
Basically, the problem with Johan's initial table was the extra empty
row at the end:

--8<---------------cut here---------------start------------->8---
#+PLOT: title:"Weight" ind:1 deps:(2) type:2d with:linespoints set:"xdata time" set:"timefmt '%Y-%m-%d'" set:"yrange [90:]"
|       Date |   Kg |
|------------+------|
| 2010-02-21 | 95.0 |
| 2010-02-22 | 93.0 |
| 2010-02-23 | 92.0 |
| 2010-02-24 | 91.5 |
| 2010-02-25 | 91.0 |
| 2010-02-28 | 92.0 |
|            |      |
--8<---------------cut here---------------end--------------->8---

With the empty row there, the "using 1:2" option to the gnuplot plot
command is not generated correctly, instead generating "using
1:xticlable(1)" which gnuplot doesn't like!  If the last row is
deleted, everything works just fine (even if February doesn't have 29
days in 2010 ;-).

HTH,
eric
