使用temporal它可以在一张幻灯片上获得过渡效果。以下示例在其中一行上创建了一个错误。
本质上：
这确实有效：node at (ONE) [select on=<1>]{ONE}
这确实有效：node at (ONE) [select on=<3>]{ONE}
这确实有效：node at (ONE) [select on=<1-3>]{ONE}
这不起作用：node at (ONE) [select on=<1,3>]{ONE}

为了按照我想要的方式对我的数据进行排序和呈现，我需要在演示文稿中以不同的方式多次显示选择。
我该如何解决这个问题才能让它正常node at (ONE) [select on=<\magic,\selected>]{ONE}工作。除了 1 和 3 幻灯片之外，其他幻灯片都正常，其中节点显示为选中状态。
答案1
问题在于<,>，里面的逗号会使 tikz 解析器感到困惑，无法将其作为键分隔符。
解决方案是将该部分括在括号中，即：
\draw
node at (ONE) [select on=<{\magic,\selected}>]{ONE}
...;
