Details:



x=y=[0 1];

## graphics_toolkit('gnuplot'); ## problem exists both in fltk and gnuplot.

graphics_toolkit('fltk'); 

figure(1);
plot(x,y);

disp("Please study the figure to see my current output. Then, press any key to
continue program execution.");

## Meta: to simulate real life, alt-tab or go to another workspace, and then
come back to the figure. The figure will be blank and will not show up at all.
You can't study the blank figure. 

aa = kbhit();

## Octave is waiting for user to study figure and hit kbhit(). In the
meanwhile, user can't see the figure at all.





## 4.2.2 from debian backports
