Re: plot3 plots surface rather than line

I've tried the example for plot3 (x, y, z), get a surface but do not
understand the graph. The graph is using a categorical variable for x (1 to
100), y goes from 0 to 2, and the z scale indicates values between -1 to +5.

Example
   z = [0:0.05:5];
   plot3(cos(2*pi*z), sin(2*pi*z), z, ";helix;");
