bug in 3.0.0 Gnu Octave

[John.Kopplin at L-3Com.com]

I need to report a bug in the 3.0.0 version of Gnu Octave (or the bug
may be in gnuplot).  I have prepared and attached a short .M file called
Bug.m which displays the bug.  This script computes a two-frequency
spectrum and then plots it in 3 views.  All 3 plots are attached as
screen captures and it is the 2nd one that is in error.  You can see
that one of the spectral peaks has completely disappeared in the 2nd
plot.  If I change the axes statement from:

 

 axis([0 Fs/2 -100 0]);

 

to:

 

 axis([0 Fs/2 -100 20]);

 

then the 2nd plot is correct.  I installed 3.0.0 Gnu Octave under
Windows using the pre-built binary from the file octave-3.0.0-setup.exe.
Thanks.
