I have used Gnuplot off and on for maybe 15 years now.  It seems that
by now, it would be possible to add a single datapoint to an existing
file.  I checked the patches, and didn't see anything there.  Is there
any interest in this?

What I do now, using a Perl interface is to maintain the queue of data
in Perl and plot a new graph for each new datapoint.  Normally this is
not a problem, but the target system is an embedded, fanless system
running at 800MHz, and doing other tasks as well.  The Gnuplot
overhead is becoming an issue.  If the queues were maintained inside
of Gnuplot, it could be made more efficient.
