Currently, draw(x,x=0..10,unit==[1.0,2.0])
does not show units by default, you have to click the control
panel button or use 'units(%,1,"on")'.
I think that by specifying "unit" options in "draw", the intention
is to show units.
This is also the case in some of the graphs in reference book,
for example in section 7.1.4 (page 234-236), where several graphs
should show units, but they didn't.
Following patch fixes this.
