[O] org-plot jumps over empty columns

[Anders Wirzenius]

Hi,
this is my first post to this newsgroup and it is a negative one (bug
report)! :-(
So I start with sending my kudos to all developers. Big thanks! :-)

Problem:
It seems that org-plot/gnuplot assumes there is a non-empty value
on each row of the table.

Org-plot/gnuplot jumps over empty columns and picks up the value
from the first non-empty column when executed.

In the example below where column 7 should be plotted, the last two
values are taken from column 8.
If I change the column to be plotted from 7 to 8, all values are
taken from column 9.

Test also plotting column 11 or 12.
