我试图将文本放在合适的位置，并尝试使用above、below、left... 和等选项pos，但我做不到。我的想法是将标签移动到新的干净位置，例如：
这是我的代码：
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath}
\usepackage{tikz}
\usetikzlibrary{positioning,calc}
\usetikzlibrary{arrows,shapes}
\tikzset{

这三个箭头位于代码中的第 280、281 和 282 行。
答案1
回应OP的询问
我认为我知道问题所在，但不知道如何解决它。当我有一个箭头在多个坐标间移动时，当我想移动标签时，它只会以箭头的最后一部分为参考移动。例如，在这个箭头中，我无法将标签定位在箭头的开头（因为开头不是箭头的“最后一部分”）：
\draw[flecha] (g7_1) -- ++ (-0.2, 9) -- ++ (-2.71, 0) -- node[below right, pos=0.9] {1} (g5_10);
提出的解决方案是-
因此将节点命令移至代码的另一部分——
\draw[flecha] (g7_1) -- ++ (-0.2, 9) node[below right, pos=0.9] {1} -- ++ (-2.71, 0) -- (g5_10);
