我创建了以下工作分解结构（WBS）图表：
最小工作示例（MWE）：
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows,shapes,positioning,shadows,trees}
\tikzset{
basic/.style = {draw, text width=5cm, drop shadow, font=\sffamily, rectangle,level distance=3cm,},
level 0/.style = {basic, rounded corners=0pt, thin, align=center, fill=black!20, minimum height=2cm},
level 1/.style = {basic, rounded corners=0pt, thin, align=center, fill=black!30, text width=8em, minimum height=2cm, sibling distance = 150mm},
level 2/.style = {basic, thin, align=center, fill=black!40, text width=8em, minimum height=2cm, sibling distance = 120mm},
level 3/.style = {basic, thin, align=center, fill=black!50, text width=6.5em, minimum height=2cm, sibling distance = 40mm},
level 4/.style = {basic, thin, align=center, fill=black!50, text width=5em, minimum height=2cm, node distance=2.5cm},
>=latex
}
\begin{document}
\begin{tikzpicture}[edge from parent fork down,->,draw,black]
% root of the the initial tree, level 1
\node[level 0] {abcd}
% The first level, as children of the initial tree
child {node[level 1] (c1) {abcd}
child {node[level 2] (c11) {abcd}
child {node[level 3] (c111) {abcd}}
child {node[level 3] (c112) {abcd}}
}
}
child {node[level 1] (c2) {abcd}
child {node[level 2] (c21) {abcd}
child {node[level 3] (c211) {abcd}}
child {node[level 3] (c212) {abcd}}
}
child {node[level 2] (c22) {abcd}
child {node[level 3] (c221) {abcd}}
child {node[level 3] (c222) {abcd}}
child {node[level 3] (c223) {abcd}}
}
};
% The second level, relatively positioned nodes
\begin{scope}[every node/.style={level 4}]
\node [below of = c111, xshift=15pt] (c1111) {abcd};
\node [below of = c1111] (c1112) {abcd};
\node [below of = c1112] (c1113) {abcd};
\node [below of = c112, xshift=15pt] (c1121) {abcd};
\node [below of = c1121] (c1122) {abcd};
\node [below of = c1122] (c1123) {abcd};
\end{scope}
% lines from each level 1 node to every one of its "children"
\foreach \value in {1,2,3}
\draw[->] (c111.195) |- (c111\value.west);
\foreach \value in {1,2,3}
\draw[->] (c112.195) |- (c112\value.west);
\end{tikzpicture}
\end{document}
现在的问题是：
我如何编辑箭头尖的大小、形状和颜色？我更喜欢带有填充形状的漂亮箭头。这些箭头的样式\textrightarrow与此图形不太匹配…… :-)
答案1
这就是arrows.meta目的。我所做的就是加载arrows.meta而不是箭头并更改>=latex为>={Latex[width=2mm,length=4mm,red]}。
\documentclass{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,shapes,positioning,shadows,trees}
\tikzset{
basic/.style = {draw, text width=5cm, drop shadow, font=\sffamily, rectangle,level distance=3cm,},
level 0/.style = {basic, rounded corners=0pt, thin, align=center, fill=black!20, minimum height=2cm},
level 1/.style = {basic, rounded corners=0pt, thin, align=center, fill=black!30, text width=8em, minimum height=2cm, sibling distance = 150mm},
level 2/.style = {basic, thin, align=center, fill=black!40, text width=8em, minimum height=2cm, sibling distance = 120mm},
level 3/.style = {basic, thin, align=center, fill=black!50, text width=6.5em, minimum height=2cm, sibling distance = 40mm},
level 4/.style = {basic, thin, align=center, fill=black!50, text width=5em, minimum height=2cm, node distance=2.5cm},
>={Latex[width=2mm,length=4mm,red]}
}
\begin{document}
\begin{tikzpicture}[edge from parent fork down,->,draw,black]
% root of the the initial tree, level 1
\node[level 0] {abcd}
% The first level, as children of the initial tree
child {node[level 1] (c1) {abcd}
child {node[level 2] (c11) {abcd}
child {node[level 3] (c111) {abcd}}
child {node[level 3] (c112) {abcd}}
}
}
child {node[level 1] (c2) {abcd}
child {node[level 2] (c21) {abcd}
child {node[level 3] (c211) {abcd}}
child {node[level 3] (c212) {abcd}}
}
child {node[level 2] (c22) {abcd}
child {node[level 3] (c221) {abcd}}
child {node[level 3] (c222) {abcd}}
child {node[level 3] (c223) {abcd}}
}
};
% The second level, relatively positioned nodes
\begin{scope}[every node/.style={level 4}]
\node [below of = c111, xshift=15pt] (c1111) {abcd};
\node [below of = c1111] (c1112) {abcd};
\node [below of = c1112] (c1113) {abcd};
\node [below of = c112, xshift=15pt] (c1121) {abcd};
\node [below of = c1121] (c1122) {abcd};
\node [below of = c1122] (c1123) {abcd};
\end{scope}
% lines from each level 1 node to every one of its "children"
\foreach \value in {1,2,3}
\draw[->] (c111.195) |- (c111\value.west);
\foreach \value in {1,2,3}
\draw[->] (c112.195) |- (c112\value.west);
\end{tikzpicture}
\end{document}
我猜你会缩小箭头，这只是为了显示你可能想要调整的两个相关参数。
