    _______________________________________________________

Details:

the following code


close all
graphics_toolkit gnuplot
rgbplot(jet(16),'composite')


will produce the same error as this other code


close all
graphics_toolkit gnuplot
image(1:8)


because plot/utils/private/__go_draw_axes__.m doesn't handle 1d images
correctly before sending the command to gnuplot.

I attach a patch that solves this issue, but is not a great solution.
