Re: plot3 plots surface rather than line

[Henry F. Mollet]

I've tested the example for plot3 using Octave 2.1.49 and I get the helix as
expected from ";helix;".
z = [0:0.05:5];
   plot3(cos(2*pi*z), sin(2*pi*z), z, ";helix;");

For results in 2.1.71 see attached (24kb PDF) which presumably must be a
"carpet" plot.
