Graphics, Figures & Tables ⇒ Specific Drawings with Arrows and Vertices

Hi there,

I would like to know how to draw the pictures from the attachment in LaTeX.

I tried all the basic stuff using coordinates and smooth lines etcetera but the resulting pictures are terrible!

All hints, tips and trick will be very much appreciated.

Kind regards,

Lemon

Hi Lemon,

Welcome to the forum!

Please show what you tried, so we can help to improve it.

Hi Stefan,

Thank you for your response. I now have this:

Code: Select all

\documentclass[11pt]{article}
\usepackage[T1]{fontenc}
\usepackage{tikz}
\usetikzlibrary{arrows}

\begin{document}
  \begin{figure}[!ht]
    \centering
    \begin{tikzpicture}[
      auto=left,
      every node/.style={
        circle,
        draw,
        fill=black,
        text=white,
        scale=1.0
      }
    ]
      \node (A) at (0, 0) {A};
      \node (B) at (0, 2) {};
      \node (C) at (0, 4) {};
      \node (D) at (-2, 6) {};
      \node (E) at (2, 6) {};

      \foreach \from/\to in {A/B, B/C, C/D, C/E}
        \draw (\from) -- (\to)[black];

      \draw [blue, very thick] plot [smooth] coordinates {(-2,6) (-3,5) (0,2)};
      \draw [red, dashed] plot [smooth] coordinates {(2,6) (3,7) (4,5) (3,3) (0,0)};

      \node [fill=none, draw=none, text=black] (X1) at (2, 1) {$e_1$};
    \end{tikzpicture}
    \caption{Example}
    \label{fig:xample}
  \end{figure}
\end{document}

Just for information to other users for awareness of possibly already existing solutions. The question has also been posted to {TeX} SX nearly at the same time and already has an accepted answer. Please read what our administrator thinks about that.

A crossposting is always contra-productive. But there is nothing really against it as long as it is mentioned. This means that a direct link has to be added. So other users who want to help are preserved from double efforts and waste of time.

Regarding the problem, you can try something like this. Click on "Open in writeLaTeX" in the below code box to see the output instantly.

Code: Select all

\documentclass[11pt]{standalone}
\usepackage[T1]{fontenc}
\usepackage{tikz}
\usetikzlibrary{arrows}

\begin{document}
    \begin{tikzpicture}[
      >=stealth,
      auto,
      point/.style={
        circle,
        draw,
        fill=black,
        text=white,
        scale=1.0
      }
    ]
      \node[point] (A) at (0,0)  {A};
      \node[point] (B) at (0,2)  {};
      \node[point] (C) at (0,4)  {};
      \node[point] (D) at (-2,6) {};
      \node[point] (E) at (2,6)  {};

      \foreach \from/\to in {A/B, B/C, C/D, C/E}
        \draw (\from) -- (\to)[black];

      \draw[->,blue,very thick] (D.135) .. controls +(left:2) and +(left:2) .. (B);
      \draw [->,red,dashed] (E.45) .. controls +(right:2) and +(right:2) .. node[midway,black] (e1) {$e_1$} (A);
    \end{tikzpicture}
\end{document}

I don't think that we will get feedback on tis. m(
