我在以下 tikzpicture 中遇到了一些问题。由于这是属于较大模型的代码示例，我无法在水平方向上扩展元素之间的距离（垂直扩展就可以了）。但是，您可以看到数字与线条重叠。您对如何解决我的问题有什么想法/建议吗？

你可以基本上确定并改变节点距离，然后摆弄节点
\node [latent] (LV1) at (0,0) {Factor};
\begin{scope}[node distance=1.5cm]
\node [manifest] (WR) [below =of LV1] {Indic1};
\node [manifest] (SI) [left = of WR] {Indic2};
\node [manifest] (IN) [right = of WR] {Indic2};
\end{scope}
\node [latent] (EIN) [below =of IN] {Error};
\node [latent] (ESI) [below =of SI] {Error};
\node [latent] (EWR) [below =of WR] {Error};
\draw [paths] (LV1) to node[midway,sloped,above] {0.999} (IN);
\draw [paths] (LV1) to node[midway,sloped,above] {0.999} (SI);
\draw [paths] (LV1) to node[midway,sloped,above] {0.999} (WR);
