Graphics, Figures & Tables ⇒ Causal Diagrams with Common Grandchild

[asmithb]

Dear all,

I want to make the the following diagram type, but with a vertical orientation:

Common Grandchild.png (3 KiB) Viewed 3067 times

Specifically, I want the 3 children from my diagram to end up having a common grandchild. So far, I have the following code but do not know how to draw the common grandchild:

You can add the node manually, use the same level distance and styles.

Code: Select all

\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{arrows.meta,positioning}
\begin{document}
\begin{tikzpicture}[
  sibling distance=6cm,
  level distance = 1.5cm,
  edge from parent/.append style={->},
  growth parent anchor=south,
  >=Latex,
  root/.style = {black},
]
% root of the the initial tree, level 1
\node [root] (root-1-1-1) {Grandpa}
  % The first level, as children of the initial tree
    child {node {Father}  
      child {node (C1){Child}}
      child {node (C2) {Child}}
      child {node (C3) {Child}}
  };
% use same level distance as above
\node [below = 1.5cm of C2.center] (C4) {Grandchild};
\foreach \kid in {C1, C2, C3} \draw[->] (\kid) -- (C4);
\end{tikzpicture}
\end{document}

Some more approaches:

with \tikzleveldistance

Code: Select all

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{arrows.meta,positioning}

\begin{document}
\begin{tikzpicture}[
  sibling distance=6cm,
%  level distance = 1.5cm,% initial value
  edge from parent/.append style={->},
  growth parent anchor=south,
  >=Latex
]
% root of the the initial tree, level 1
\node {Grandpa}
  % The first level, as children of the initial tree
    child {node {Father}  
      child {node (C1) {Child}}
      child {node (C2) {Child}}
      child {node (C3) {Child}}
  };
% use same level distance as above
\node [below = \tikzleveldistance of C2.center] (C4) {Grandchild};
\foreach \kid in {1, 2, 3} 
  \draw[->] (C\kid) -- (C4);
\end{tikzpicture}
\end{document}

with another child

Code: Select all

\documentclass[tikz,border=10pt]{standalone}
\usetikzlibrary{arrows.meta}

\begin{document}
\begin{tikzpicture}[
  sibling distance=6cm,
%  level distance = 1.5cm,% initial value
  edge from parent/.append style={->},
  growth parent anchor=south,
  >=Latex
]
% root of the the initial tree, level 1
\node {Grandpa}
  % The first level, as children of the initial tree
    child {node {Father}  
      child {node (C1) {Child}}
      child {node (C2) {Child}
        child {node (C4) {Grandchild}}
      }
      child {node (C3) {Child}}
  };
\foreach \kid in {1, 3} 
  \draw[->] (C\kid) -- (C4);
\end{tikzpicture}
\end{document}

[asmithb]

Thank you very much. I have other question.

How do I add a grand grandchild to the bottom. What about if I want to add 3 grand-grandchild and then one common grand-grand-grandchild as you did above?

Thanks again

[asmithb]

How could I move the grandchild and the grand-grandchild to the middle of the diagram?
