Yes - I was using ob-gnuplot approximately in the complete second half
of this thread.  And it is indeed the better choice for my case.

The quoting problem you quoted above originates from org's table export,
though.  This quoting is hard to avoid, not without a hack, and
independent from the used "export tool".

My final solution for this little remaining problem is to tell gnuplot
to expect a time value wrapped in quotes:

| plot data using 1:(timecolumn(2,"\"%H:%M\"")) with ...
                                   ^^     ^^

Thx,
