Details:

Executing the following


figure
set (gca, 'yscale', 'log')


doesn't work with either gnuplot or OpenGL+FLTK grahpics.  With gnuplot, I see
an error from gnuplot:


octave:1> set (gca, 'yscale', 'log')
octave:2>          line 2: y range must be greater than 0 for log scale


and with OpenGL+FLTK, I see an empty figure window.  I think axes should be
displayed and default limits should be set appropriately for the axes with log
scales, for example to [.1, 1] (whatever is compatible with Matlab).
