如果我能得到箭头方面的帮助，我想我可以自己做标签。谢谢

在大家的帮助下，我能够做到这一点，感谢所有帮助者

答案2

图表

我尝试按照手绘的顺序来。

  • 平行edges是通过分别控制节点边界上的离开角和进入角来构建的。
  • 有一些用于表示有趣箭头的幻影节点；它们是使用样式引入的cBox。
  • 我只写下了箭头上的一些标签；这是一个起点。

答案4

我建议tikz-cd（这里通过cd图书馆加载）。

虽然 TikZ-CD 提供了按键shift left和shift right（与箭头键一起使用）电视和大号) 这些通常只适用于没有边界的节点。考虑到节点边界的节点之间的平行线并不简单。

值得庆幸的是，变换键xshift和yshift已超载，可变换整个箭头（→shift up等）。但对于某些箭头，您仍然需要这些ortho键。

对于之间的箭头电视和A，这个角度实在是太烦人了，手动选择边框上的每个点会更容易。在这里，我只移动其中一个箭头，让另一个箭头保持其自然位置。（这意味着这两个箭头的位置不对称，但谁会注意到呢？）

对于之间的连接年代和A也C和A我也选择了正交连接。其他节点或箭头会妨碍连接。
