tikz矩阵对齐问题

我正在尝试解释 SAD（绝对差值总和）。经过大量调整后，我得到了一些看起来还不错的东西，只是水平和垂直对齐/距离很糟糕！而且，正如您所见，所有内容都是硬编码的。

我怎样才能让一切都排列整齐？

标签右侧未与 对齐Left，以及Center3 个“行”之间的垂直距离。Left, Center & Right矩阵可能应该向右移动一点，以使所有内容都集中在某个假想的垂直轴上。添加可重复的偏移直到看起来更好是一件麻烦事，因为有很多值需要更改，例如对于网格。

答案1

这是一个非常不同的版本，其中没有明确的位置。center首先定义矩阵，然后相对于此放置另一个矩阵。这给出了矩阵（边缘）之间的一致距离。您可以通过更改node distance我添加到tikzpicture选项中的键来修改间距。第一个值是垂直间距，第二个是水平间距。positioning添加库以允许这种类型的定位。

的垂直对齐Right是通过在每个标签节点上添加一个来固定的text depth（类似于逗号对齐问题）。

要向节点添加选项，matrix of nodes您可以将其添加|[<options>]|到单元格的开头。我用它来制作一些值|[red]|。（事后看来：对于right矩阵，您可以直接将red选项添加到矩阵中。对于search您还可以修改column 3/ column 4/column 5样式，而不是修改这些列中的每个单元格。）

我还添加了几个样式，以减少代码重复。

网格是在矩阵之后绘制的，但是在backgrounds库的帮助下在背景层上绘制。

您可以使用scope环境和xshift参数：
