Follow-up Comment #5, bug #41583 (project octave):

That's really strange.  I run Kubuntu 12.04 and the FLTK results are very
good.  It has been so good that the default toolkit was switched in 3.8 over
to FLTK from gnuplot.

I don't recall anyone having trouble with the FLTK toolkit on Linux so it may
be something odd about your particular system.  Perhaps you don't have an
OpenGL capable video card and are relying on a software implementation like
Mesa instead.  I agree that the plot you made, fltk.png, is rather awful.  It
appears that no OpenGL lines are being drawn.  This would account for why the
axes are not shown and also why the sine plot shows each individual point
rather than having smooth connecting lines between point.

You might try something simpler like

plot (1:10, "o-");

and see what it produces.
