对于代码和图像，我想将线条从子节点变成父节点的虚线箭头。我尝试使用边缘构造parent[->, dashed]，但做不到。我不需要形状或框中的节点，也不需要彩色线条。
谢谢，
大卫

请以良好的格式组织您的代码。
使用edge from parent/.style={draw, dashed, <-}来获得虚线箭头。
\documentclass[tikz, border=1cm]{standalone}
\tikzstyle{bag} = [align=left]
\begin{document}
\tikz [font=\small,
grow=left,
level 1/.style={sibling distance=12em},
level 2/.style={sibling distance=3em},
level distance=5cm,
edge from parent/.style={
draw, dashed, <-,
}
]
\node[bag] (n00) {Process Description} % root
child { node[bag] (n01) {Connectivity\\ From Process Knowledge}
child { node[bag] (n02) {Process Layout}}
child { node[bag] (n03) {Structural Modelling}}
child { node[bag] (n04) {Adjacency Matrices}}
}
child { node[bag] (n05){Causality \\From Process Data}
child { node[bag] (n06) {Cross Correlation}}
child { node[bag] (n07) {Granger Causality}}
child { node[bag] (n08) {Information Theory}}
child { node[bag] (n09) {Bayesian Networks}}
child { node[bag] (n10) {(Machine Learning)}}
};
\end{document}
