Maybe I'm missing the point of the :missing header, but I find it
easier and clearer to include the datafile missing command in the
gnuplot code block. I don't really see a need for the :missing
header. Maybe the need stems from wanting to be able to use different
plotting packages to plot
I agree that it is easier and more clear to include set datafile
missing... in the body of a gnuplot code block. I *do* think that the
:missing header argument has value specifically as a way to replace
missing values in the original table data.
I've changed the behavior of the :missing
Hi Eric,
Currently the :missing header argument for gnuplot code blocks does two
things. It adds the set datafile missing... line to the code block
body *and* it binds `*org-babel-gnuplot-missing*' to the value of the
:missing header argument when the datafile is written, so empty table
Hi Eric,
There appears to be a slight bug in the way gnuplot handles blocked
data with missing entries.
An example is provided in the org script at then end of this note.
In the code block gnuplot_1 the use of ':missing ?' seems to cause
the exported data file to lack the blanks lines that are

Dear Eric,
Recently you made some nice changes to the way gnuplot plots surface
data from org tables. Your changes are present on
git://orgmode.org/org-mode.git, but I switched to using ELPA recently
and I've just noticed that your changes are not yet present on
http://orgmode.org/elpa/. Do you

ELPA doesn't lag anything like three months. However, it is tracking
maint, not master.

I've implemented calculation separators that register as hlines for
table formulas, but are ignored when row groups are constructed for
export. Your example table would then look like this:
Achim,
just to apologise for not getting back to you
I would consider this breaking the plot, in that gnuplot no longer lines
up the two columns of data.
My fault, gnuplot does indeed still line up the data as appropriate when
missing values are simply replaced with blank space rather than .
I've just pushed up changes to gnuplot code blocks
Hi Eric,
Thanks for your work on this. I've tried your latest changes and I
think they're a big improvement.
I've attached another org-mode file for you to try. It illustrates
the use of double blank lines in the first table (called block_data)
to inform gnuplot that there're two separate data
Hi Eric,
That's seems perfect now; I can't see any other issues. Thanks!
Kind regards,

What you suggest is indeed a good solution, so thank you very much for that!
I think it would still be nice, however, if someday the blank lines in
