对 3D 坐标系统的困惑

Question

我正在绘制一个 3d 框架。我使用类似(xyz cs:x = 12, y = 6, z = -6)来指定坐标。但是，我制作的图形看起来很丑。
特别是，虚线蓝绿色角落的坐标与 的刻度不一致z-axis（参见顶角点和Quantify的刻度）z-axis。笔记：正如@Torbjørn T. 在评论中指出的那样，这是由于一个愚蠢的错误造成的。不过，我仍然对以下更普遍的问题感兴趣。）

我怎样才能改善它更多的3D 吗？

Answer 1

这里有一个想法，教你如何做到这一点。另外，\foreach这也是你的朋友 ;)

标题

\documentclass[tikz, border=2mm]{standalone}

\begin{document}

\begin{tikzpicture}
[   x={(-10:1cm)},
    y={(220:1cm)},
    z={(90:1cm)},
    scale=3,
]
    \draw[-stealth] (0,0,0) -- (2.2,0,0) node[pos=1, above right] {Consistency models};
    \draw[-stealth] (0,0,0) -- (0,2.2,0) node[pos=1, below left] {Data Types};
    \draw[-stealth] (0,0,0) -- (0,0,2.2) node[pos=1, above right] {Assurance Models};

    \foreach \z in {0,...,2}
    {   \draw[teal, densely dashed, very thick] (0,0,\z) -- (2,0,\z) -- (2,1,\z) -- (0,1,\z) -- cycle;
        \node[blue, circle, fill, inner sep=2pt, label=-45:(2.\z)] at (2,1,\z)  {};
    }

    \foreach \x/\y in {0/0, 0/1, 2/0, 2/1}
    {   \draw[teal, densely dashed, thick] (\x,\y,0) -- (\x,\y,2);
    }

    \foreach \c/\x/\y/\z in {1/Weak/Register/Maintain,2/Strong/Transaction/Quantify}
    {   \node[below left, font=\footnotesize] at (\c,0,0) {\x};
        \node[circle, fill, inner sep=1pt] at (\c,0,0) {};
        \node[above left, font=\footnotesize] at (0,\c,0) {\y};
        \node[circle, fill, inner sep=1pt] at (0,\c,0) {};
        \node[left, font=\footnotesize] at (0,0,\c) {\z};
        \node[circle, fill, inner sep=1pt] at (0,0,\c) {};
    }
\end{tikzpicture}

\end{document}
