Details:



When plotting the colorbar with gnuplot, the colorscheme is reversed. When
using fltk, and qt, the colorscheme is fine (see attachedments. The following
script was used to generate the figures.  

x=reshape(0:24,5,[])/24;
for g = {'fltk','gnuplot','qt'}
        close all
        graphics_toolkit(g{1})
        imagesc(x); colorbar
        print('-dpng',sprintf('5x5.%s.png',g{1}))
        pause(1)
end;
