编辑：编译代码的序言

包中是否有任何内置方法tikz可以相对于另一组或文档的页面移动/定位一整组路径和节点？

为了说明我的意思，以下是我正在做的事情：

如您所见，我将一个不同的绘图放在另一个绘图旁边。但我认为我实现它的方式不是最简单/最优雅的解决方案：我使用了tabular。

\captionof{figure}{Angles $ \alpha,\beta,\gamma,\delta $} that correspond to $ a,b,c,d $ respectively. $ \varepsilon $ represents a positive infinitesimal.
\label{angles}

\end{minipage}

此外，在每个坐标中我tikzpicture必须定义相同的坐标(A)、(B)和。(C)(D)

有没有更好的方法来做到这一点，在同一个范围内tikzpicture？

在这种情况下，寻找替代解决方案似乎相对简单且没有必要，但这只是因为此处的预期定位很简单：两幅画，一幅挨着一幅。但想象一下，我们必须放置三、四幅图像，并且必须以特殊方式定位它们——例如，每幅图像位于正多边形的顶点。

编辑：如果您确实需要以奇怪的方式定位它们，您可以将您的tikzpictures 嵌套在一些nodes 中，并将它们相对定位。我不知道这对您来说是否有用，甚至是否推荐，但它可能会有所帮助。

答案2

  • 对于您的图像的基础，我使用了我在您的回答中的代码上一个问题
  • 为了使完整图形的代码更短，我定义了包含两个图像的公共部分的新命令
  • 图像由它们定位\centering在\hfil它们之间：

您不需要表格，您可以tikzpictures像任何其他字母一样将两者放在一起：
