Johan,
I've played with this a bit and I also cannot get it to work.
However, looking at the gnuplot comint buffer created, there is an
error message that indicates that plotting xdata in time format
requires a using statement to specify directly the columns to plot. I
have tried, therefore, the following specification on the plot line:
--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:]" ind:1 deps:(2)
| 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 |
| 2010-02-29 | 92.0 |
--8<---------------cut here---------------end--------------->8---
I had to put quotes around the time format and also (just in case)
spelled out linespoints fully. However, this still doesn't work
because org-plot/gnuplot generates the following plot command:
,----
| plot '/tmp/org-plot1831zcQ' using 2:xticlabel(1) with linespoints title 'Kg'
`----
Note the strange using parameters! I am not sure where this is coming
from unfortunately. Note that if I type this in directly in gnuplot,
with "using 1:2", everything works just fine.
