Octave doesn't yet include support for gnuplot's html5 terminal.

I'll need to look at the appropriate gnuplot docs to include it. Can you tell 
me which version of gnuplot has this terminal ?

If you're interested in trying to modify Octave to enable the htlm5 terminal, 
the sources to patch are ...

        __gnuplot_drawnow__.m: gnuplot_set_term()
        __gnuplot_drawnow__.m: gnuplot_is_enhanced_term()

Once html5 is added there, you can produce a plot with ...

        plot (rand (3))
        drawnow ("html5", "plot.html5", false, "/dev/null")

I've been considering modifying __gnuplot_drawnow__.m to support gnuplot 
terminals that are not explicitly supported by Octave. Perhaps this is an 
opportunity to me to do that.

To add html5 support the print(), then the sources to modify include ...

        print.m
        __gnuplot_print__.m
