Graphics, Figures & Tables ⇒ Graph Binomial Tree

[deadCat]

Hey Guys,

I'm trying to create a binomial tree. It should look like
so that the rightmost edge is vertical.

The code, which I have is

Code: Select all

\begin{tikzpicture}[every tree node/.style={draw,circle},
   level distance=1.25cm,sibling distance=.5cm, 
   edge from parent path={(\tikzparentnode) -- (\tikzchildnode)}]
\Tree [.\node[red] { }; 
    [.{ }  
      [.{ }
        [.{ }  [.{ } ]
        ] [.{ } ] 
      ]
      [.{ }  [.{ } ]
      ] 
      [.{ } ]
    ]
    [.{ }
      [.{ }  [.{ } ]
      ] [.{ } ] 
    ] 
    [.{ }  
      [.{ }  ]
    ]
    [.{ }  ] 
    ]
\end{tikzpicture}

but the result is as you see in the attachment. Is there a way to get a vertical edge?
THX

Welcome to the forum!

I guess your question remained unanswered because the example code is not running with TikZ. I tried it, and I got the error message

Code: Select all

! Undefined control sequence.
l.11 \Tree
           [.\node[red] { };

I assume you are using a specific library or another package, such as tikz-qtree. Loading the latter makes the code compilable, if I add a document frame as well. Perhaps post a minimal working example next time, so readers could test and improve.
