Hi Paul,
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
cells are replaced with the value of the :missing header argument.
The reason you're not getting a blank line is because it is replaced
with three "missing" values, in this case "? ? ?".
Do you think this behavior should be changed or split between two header
arguments?
Thanks,
