Dear maintainers,
the following
semilogy([0,0])
produces an empty window (without axes) in Octave 3.2.2 (though I remember
that some days ago it produced nothing, as in Octave 3.0.5, I cannot
explain why) and no warning about nonpositive data.
With the enclosed patch the axes are computed is a quite ml compatible way
and the warning is there. As a ChangeLog I would say
2009-08-07 Marco Caliari <address@hidden>
* graphics.cc (get_array_limits): set min_pos value to 0.1
if data are nonpositive.
Best regards,
Marco
