It's not related to the test itself, but line
  hf = figure (gcf (), "__graphics_toolkit__", "fltk", "visible", "on");
fails for me. I need to add 'graphics_toolkit fltk' in the first line to make 
it work.


If the test in run in script mode, it always pass. While testing Rik's plot 
issue I realized, that subplot is not neccessary for catching the y-axis bug. 
The optical difference is not as big as with subplot, so I overlooked it in the 
past. With attached patch the bug is reproducable in script mode. Please note 
the 'sleep(2)' after the plot command. Without this sleep, the test pass 
without error.

PS: Over night I updated from fltk 1.1 to 1.3. It doesn't affect the bug.
