hmm ... I may have got the command wrong. I'm running development code for 
gnuplot, and it is a bit dated. Try ...

        drawnow ('lua', 'plot.tikz', false, 'gnuplot.gp')

A more complicated solution would be to ..

        drawnow ("x11", "/dev/null", false, "gnuplot.gp")

Then (1) edit gnuplot.gp and replace the "x11" terminal specification with 
"lua". (2) Modify or add a "set output ...." line to read "set output 
plot.tikz". (3) type "gnuplot gnuplot.gp" form a terminal window. That should 
produce your result.

I'm in a rush at the moment, so my instructions are from memory and I did not 
test them.
