有问题
在（一堂课）结束时，这是我想要显示的完整图表。
但在课堂上，我会一步步地只有节点和箭头在“案例编号”区域（就像最后的顿悟一样，不同的区块都是连接在一起的）。
我的问题
以案例 1 为例。首先，我只想显示严格位于红色区域中的节点和箭头（不显示指向其他节点的箭头，也不显示区域外的其他节点）。但如果我执行简单的操作\ifBlock1true，我当然会遇到来自 3-2 和 4-3 的箭头带来的麻烦。
对于每一种情况，\newif我都会遇到箭头问题，最终需要在完整的图表中显示出来。
编辑1
正如您所见，@Schrodingerscat 的精彩答案重新创建了与visible onoutside相同的内容beamer。
正如评论中所讨论的那样，将这些图形逐块插入或中作为单个图形article将book留下空白，节点的白色阴影尚未显示。（解决方案 1）。我愿意拥有可以用调用的单独块。然后将每个块放在或\def\Block{i} \input{Maingraph}中的图形（居中）。这是解决方案 2。articlebook

答案1
visible on这是库中附带的nice 样式的 poor-cat 版本beamer-overlay-styles。您可以为每个元素分配一个类，以控制其可见性。这class={1,3}意味着元素显示在第一个和第三个覆盖层上。如果您进行 beamer 演示，您可以加载库beamer-overlay-styles，忘记所有这些class东西并改用visible on=<1,3>。但是，如果您不仅更改可见性，而且在不同的幻灯片上有不同的元素，您可能仍然对样式感兴趣recycle bounding box，就像\pause和\ifnums 中发生的那样。

稍加修改，您就可以将“覆盖”缩小到各自的大小：在覆盖模式下绘制事物，然后仅选择边界框以包含您真正想要的东西。
