pgfplots 仅绘制奇数 3d 段

Question

给出如下的三维坐标表：

x1 y1 z1  
x2 y2 z2  
x3 y3 z3  
x4 y4 z4 

我希望用一条\addplot3命令打印从第一个点到第二个点、从第三个点到第四个点等等的段，如下所示：

(x1, y1, z1)->(x2, y2, z2)
(x3, y3, z3)->(x4, y4, z4)

而不是连接点 2 到 3、点 4 到 5 等等的线段。

我怎样才能实现这个目标？

目前我被困住了

由该代码给出：

\documentclass[10pt, border=5pt]{standalone}

\usepackage{ifthen}
\usepackage{pgfplots}
\pgfplotsset{compat=1.11,
             height=15cm
             }
\usetikzlibrary{positioning}


\begin{document}
    \begin{tikzpicture}

            unit vector ratio=1 1 1,
            ymin=-0.15, ymax=0.15
            ]%
            \addplot3[
                blue,
            ]
            table [x={x1}, y={x2}, z={x3}] {statex.dat};

            \addplot3+[
