Try doing

    graphics_toolkit gnuplot

before plotting anything.

The problem is that this Windows version of Octave is using the fltk
backend by default, which is very slow for plotting moderately
complicated plots.

In addition, I think the 'hiding the plot' trick didn't work with fltk at all. it wouldn't update any non-visible plots.
