pgfplot：从点到 x 轴添加线

Question

我是 pgfplot 和 latex 自动化的新手。我正在绘制一个 3d 散点图，如附图所示。我想从每个点到底面画一条线（因此 z = 0，x 和 y 是点坐标）。这些点来自 CSV 文件。有没有办法不用手动绘制每条线就可以完成我想要的操作？非常感谢您的帮助。

编辑：这是我的代码，抱歉遗漏了。

\usepackage{tikz}
\usepackage{pgfplots}

\begin{document}

\begin{tikzpicture}
\begin{axis}[xlabel = x ylabel = y, zlabel = z, title=test, grid=major, grid style = {dashed, gray!30}, ymin=0, ymax=1, ylabel style={rotate=90}]
    \addplot3+[only marks] table[col sep=comma] {Results_CSV/F6/data.csv};
\end{axis}
\end{tikzpicture}

\end{document}

以下是一些要点：

54,0.025,0.025
39,0.05,0.05
34,0.075,0.075
32,0.1,0.1
32,0.125,0.125

其中第一、第二和第三行分别是 x、y 和 z 轴。

欢迎使用 TeX-SE！有人指出这里此处ycomb有效。全部功劳归于汤姆·邦巴迪尔。飞机只是为了引导视线。
