我想要实现以下目标:
但节点连接不正常。我得到以下输出:
我该如何解决这个问题以及我哪里做错了。
梅威瑟:
\documentclass[tikz]{article}
\usepackage{tikz}
\tikzset{square/.style = {
shape = rectangle,
fill = gray!50,
draw = black,
thick
}}
\tikzset{circle/.style = {
shape = circle,
fill = blue!20,
draw = blue,
thick
}}
\begin{document}
\begin{tikzpicture}
\draw[square] (-4,4)rectangle node (r1) {r1} (-3,5);
\draw[circle] (-1,4.5) circle [radius=0.5cm] node (s1) {s1};
\draw[->] (r1.west) -- (s1.east);
\end{tikzpicture}
\end{document}
请注意,我想坚持\draw[->] (r1.west) -- (s1.east);
答案1
正确的图片
\documentclass[tikz,margin=3mm]{standalone}
\tikzset{squarenode/.style = {
shape = rectangle,
fill = gray!50,
draw = black,
thick,
minimum size=1cm %%%% Take note of this!
},
circlenode/.style = {
shape = circle,
fill = blue!20,
draw = blue,
thick,
minimum size=1cm %%%% and this!
}}
\begin{document}
\begin{tikzpicture}
\draw (-4,4.5) node[squarenode] (r1) {r1}; % Or \node[squarenode] (r1) at (-4,4.5) {r1};
\draw (-1,4.5) node[circlenode] (s1) {s1}; % Or \node[circlenode] (s1) at (-1,4.5) {s1};
\draw[->] (r1) -- (s1); % or (r1.east)--(s1.west);
\end{tikzpicture}
\end{document}
一些注意事项(重要!)
circle
是已定义的选项,因此您不能定义新的circle
。我将其更改为circlenode
。- 您不必手动绘制圆形和正方形。您可以使用节点和中的形状
minimum size
。为了获得更多控制,我们有minimum height
和minimum width
。 - 我不建议使用太多
\tikzset{}
s。 tikz
不是 的选项article
。它是 的选项standalone
。当您已经加载tikz
选项时,您不需要\usepackage{tikz}
。
使用(r1)--(s1)
和时的区别(r1.east)--(s1.west)
\documentclass[tikz,margin=3mm]{standalone}
\begin{document}
\begin{tikzpicture}
\node[draw] (a) at (0,0) {Some text};
\node[draw] (b) at (5,3) {Hello world};
\draw[thick] (0,0)--(5,3);
\draw[red] (a)--(b);
\draw[blue] (a.east)--(b.west);
\end{tikzpicture}
\end{document}
仔细观察红线和蓝线的起点和终点。
