(simplified example)
set dataf missing '?'
$dat << EOD
No Maybe
0 2
1 ?
2 1
3 2
4 ?
5 9
6 ?
? 1
8 2
9 5
EOD

plot "$dat" using "No":"Maybe" w lp # missing dp are invalid
pause -1
plot "$dat" using 1:2 w lp    # works



There are few connecting lines and no bezier curve, because an
invalid datapoint breaks those connections.

Aaand you know about that and "set datafile missing '?'", meaning
the connections should not be broken.

I find that it works if I use column numbers instead of header
strings in the "using" specifier. Looks like a bug to me.
