我正在寻找一种方法来使逻辑门内的文本变得更大。
这是我的代码：

结果如下：
电路尚未完成，但我认为问题很明显：或门内的文本太小。
有没有办法让它变大？如果没有，最好将其移动到门上方，以便即使文本是正常大小，也可以使它们变小。
感谢您的耐心。
答案1
门内的空间是有限的，字体大小会减小——为什么不试试门的输出呢？无论如何，它都是 4 个输入的总和
将以下内容添加到您的代码中
\draw (t1.output) -- node[above]{$x+y+z+\bar{w}$} ($(t1) + (1.5, 0)$);
答案2
您可以使用以下方法缩放标签中的字体大小{\Large{$x+y+z+\bar{w}$}}，但这会影响门的大小并需要重新定位。我对此的看法是使用节点定义内的标签并相应地缩放门。文本位于门的顶部，但如果您需要，可以使用角度编号和冒号选择您想要的角度，例如现在它相当于标签=90:$myLabel$ 请参阅下面的示例
