Graphics, Figures & Tables ⇒ Lines in 3D Space

[DanLamb]

I expected the following to render two lines: (y=1,z=3) and (y=2,z=5)

Code: Select all

\begin{tikzpicture}
  \begin{axis}[
    3d box=complete,
    grid=major,
    xlabel=$x$,
    ylabel=$y$,
    zlabel=$z$,
    samples=5
  ]
    \addplot3[color=red,domain=0:200,y domain=1:1,samples=201,samples y=1,variable y=\y] {3};
    \addplot3[color=green,domain=0:200,y domain=2:2,samples=201,samples y=1,variable y=\y] {5};
  \end{axis}
\end{tikzpicture}

Yet y is always zero. Also, how do I render z=y. I tried using {\y}, but that errors.

I basically want to render lines in 3D space and it doesn't seem to work. I've also done several dozen Internet searches and read through the documentation before posting this.
