Details:

Gnuplot 4.4 has introduced an html5 capabel terminal named "canvas". 

Some demos: http://gnuplot.sourceforge.net/demo_canvas/

To modify Octave to enable the htlm5 terminal, the sources to patch are
below.

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

Once "canvas" is added there, a plot can be produced a by the command below.


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


It should be possible to modify __gnuplot_drawnow__.m to support gnuplot
terminals that are not explicitly supported by Octave. Perhaps this is an
opportunity to do that.

To add html5/canvas support the print(), then the sources to modify include
those below.

       print.m
       __gnuplot_print__.m
