我该如何更改这张 tikz 图片？

我查找并获取了绘制立方体的代码，但现在我无法将其居中。我想将立方体进一步划分为更小的部分，如下所示： 在此处输入图片描述

如果我可以只画线而不是小立方体来表示分割，那就没问题了。这是我的图像： 在此处输入图片描述

我也无法在图像上添加我想要的标签。我希望能够根据自己的需求为所有三个轴提供标签。这是我的代码，你能帮我吗？

\newcommand{\Depth}{5}
\newcommand{\Height}{5}
\newcommand{\Width}{5}
\begin{tikzpicture}
\centering
\coordinate (O) at (0,0,0);
\coordinate (A) at (0,\Width,0);
\coordinate (B) at (0,\Width,\Height);
\coordinate (C) at (0,0,\Height);
\coordinate (D) at (\Depth,0,0);
\coordinate (E) at (\Depth,\Width,0);
\coordinate (F) at (\Depth,\Width,\Height);
\coordinate (G) at (\Depth,0,\Height);

\draw[] (O) -- (C) -- (G) -- (D) -- cycle;% Bottom Face
\draw[] (O) -- (A) -- (E) -- (D) -- cycle;% Back Face
\draw[] (O) -- (A) -- (B) -- (C) -- cycle;% Left Face
\draw[] (D) -- (E) -- (F) -- (G) -- cycle;% Right Face
\draw[] (C) -- (B) -- (F) -- (G) -- cycle;% Front Face
\draw[] (A) -- (B) -- (F) -- (E) -- cycle;% Top Face
\end{tikzpicture}

只需通过嵌套循环定义您放置的图片即可。着色可以通过\ifnums 完成。最麻烦的部分是从屏幕截图中插入文本。

如果您想知道是否可以使用更现实的投影，答案是肯定的。

这是一个带有完整立方体的版本。

请注意，pgfplots有一个3d cube情节标记，您可以使用它以更结构化的方式获取类似的情节。
