# Drawing ellipsis in networks in Tikz

I have the following basic code. I need to draw a network as follows. Can someone amend this code for me?

MWE:

\documentclass{article}

\usepackage{subcaption, pgf, tikz,geometry, hyperref}
\geometry{left=1in,right=1in,top=1in,bottom=1in}
\usepackage{tikz}
\usetikzlibrary{arrows, automata, calc}

\begin{document}
\begin{figure}
\centering

\begin{tikzpicture}[
> = stealth, % arrow head style
shorten > = 1pt, % don't touch arrow head to node
auto,
node distance = 3cm, % distance between nodes
semithick % line style
]

\tikzstyle{every state}=[
draw = black,
thick,
fill = white,
minimum size = 4mm
]
\node (a) {...};
\node[state] (b) at ($(a) + (0:2)$) {m};
\node (a0)  at ($(b) + (90:1)$) {};
\node (c) at ($(b) + (0:2)$) {...};
\node[state] (d) at ($(a) + (-45:1.5)$) {j};
\node[state] (e) at ($(b) + (-45:1.5)$) {k};
\node[state] (f) at ($(d) + (-45:1.5)$) {i};

\path[] (a) edge node {$\dots$} (b);
\path[] (b) edge node {$\vdots$} (a0);
\path[->] (a) edge node {} (d);
\path[->] (b) edge node {} (d);
\path[->] (b) edge node {} (e);
\path[->] (c) edge node {} (e);
\path[->] (d) edge node {} (f);
\path[->] (e) edge node {} (f);
\end{tikzpicture}

\end{figure}

\end{document}


My result is:

• Welcome to TeX.SX! I think your result and your image are quiet the same. What is missing? Do you need ellipsis instead of circles? Oct 19, 2017 at 13:37
• Thanks @Bobyandbob. I do not want the lines next to $m$. I want the dots at the same location as my handmade figure. Oct 19, 2017 at 13:41
• Replace \path[] (a) edge node {$\dots$} (b); \path[] (b) edge node {$\vdots$} (a0); with \node (nord) at ($(b) + (90:0.7)$) {\vdots}; You could use\node (a) {\dots}; instead of \node (a) {...};. Oct 19, 2017 at 15:39

edge command draws a line by default, if you don't want it use edge[draw=none]. But this option won't draw dots where you want.

As an alternative solution I propose following code. It shows some changes respect the original one:

The result looks like:

And the code:

\documentclass{article}

\usepackage{subcaption, pgf, tikz,geometry, hyperref}
\geometry{left=1in,right=1in,top=1in,bottom=1in}
\usepackage{tikz}
\usetikzlibrary{arrows, automata, calc, positioning}

\begin{document}
\begin{figure}
\centering

\begin{tikzpicture}[
> = stealth, % arrow head style
shorten > = 1pt, % don't touch arrow head to node
auto,
node distance = 3cm, % distance between nodes
semithick, % line style
every state/.style={
draw = black,
thick,
fill = white,
minimum size = 4mm
}
]

\node (a) {\dots};
\node[state, right=2cm of a] (b) {m};
\node[right=2cm of b] (c) {\dots};
\node[above=1mm of b] {\vdots};
\node[state, below left=1cm and 1cm of b] (d) {j};
\node[state, below right=1cm and 1cm of b] (e) {k};
\node[state, below right=1cm and 1cm of d] (f) {i};

\path[->] (a) edge node {} (d);
\path[->] (b) edge node {} (d);
\path[->] (b) edge node {} (e);
\path[->] (c) edge node {} (e);
\path[->] (d) edge node {} (f);
\path[->] (e) edge node {} (f);
\end{tikzpicture}
