在 Tikz 中移动表格的多边形和中心数字

在 Tikz 中移动表格的多边形和中心数字

我对为练习创建的表格有几个疑问。

  1. 圆圈内的数字。如何让它们居中?
  2. 我想将紫色多边形稍微向左和向下移动一点。
  3. 有没有更简单的方法来制作表格。请记住,我使用 Tikz 在表格顶部绘图,并且我还需要进行多次迭代。

提前谢谢了!

  • 加载 TikZ 库。它允许您为和之间的点calc写入。($(a)!0.5!(b)$)(a)(b)
  • 将带圆圈的数字绘制为带圆圈的节点,而不是拟合节点。
  • 用相对于起点的坐标定义多边形,然后可以通过移动起点来移动它。
  • 使用\foreach循环避免重复。
  • 绘制矩形多边形时,可以使用-||-代替 来删除每个第二个节点--
