Graphics, Figures & Tables ⇒ A figure with arrows

[Lanchester]

Hey guys,

I think I need to make use of your help another time.

Could you help me building this figure? (Attachment)

Thanks in advance.

You can get that using tikz. If you need some pointers to that, take a look at TeXamples.net.

Hi,

here's a quick straightforward TikZ way.

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{calc,positioning,quotes}
\begin{document}
\begin{tikzpicture}[
  base/.style = {circle, draw, inner sep = 1ex, font=\sffamily},
                 align = center]
  \draw [-stealth]
    node [base] (U) {U\\Artillery}
    node [base] (X) [right = 1.8cm of U] {X\\Infantry}
    node [base] (Y) [right = 1.8cm of X] {Y\\Infantry}
    node [base] (V) [right = 1.8cm of Y] {V\\Artillery}
    (U) edge[bend left, "$\alpha(t)$"] (X)
    (X) edge[bend left, "$b(t)$"] (Y)
    (Y) edge[bend left, "$a(t)$"] (X)
    (V) edge[bend left, "$\beta(t)$"] (X.south east)
  ;
\end{tikzpicture}
\end{document}

the base drawing works pretty good, but when it comes to use the tikzpackage "quotes", the whole thing collapses.

Overleaf is fine with it.

I've deleted a group-closing symbol because it seems to be
spurious, as in `$x}$'. But perhaps the } is legitimate and
you forgot something else, as in `\hbox{$x}'. In such cases
the way to recover is to insert both the forgotten and the
deleted material, e.g., by typing `I$}'.

I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.

Runaway argument?

Here is the code without the quotes library:

Code: Select all

\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc,positioning,quotes}
\begin{document}
\begin{tikzpicture}[
  base/.style = {circle, draw, inner sep = 1ex, font=\sffamily},
                 align = center]
  \draw [-stealth]
    node [base] (U) {U\\Artillery}
    node [base] (X) [right = 1.8cm of U] {X\\Infantry}
    node [base] (Y) [right = 1.8cm of X] {Y\\Infantry}
    node [base] (V) [right = 1.8cm of Y] {V\\Artillery}
    (U) edge[bend left, label = {$\alpha(t)$}] (X)
    (X) edge[bend left, label = {$b(t)$}] (Y)
    (Y) edge[bend left, label = {$a(t)$}] (X)
    (V) edge[bend left, label = {$\beta(t)$}] (X.south east)
  ;
\end{tikzpicture}

Now the labels get stacked above the circle on the left, not on the arrows (as planned).

Is there any other way to name the arrows correctly?

[Stefan Kottwitz]

Then with nodes above or below edges:

Code: Select all

\documentclass[border=10pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc,positioning,quotes}
\begin{document}
\begin{tikzpicture}[
  base/.style = {circle, draw, inner sep = 1ex, font=\sffamily},
                 align = center]
  \draw [-stealth]
    node [base] (U) {U\\Artillery}
    node [base] (X) [right = 1.8cm of U] {X\\Infantry}
    node [base] (Y) [right = 1.8cm of X] {Y\\Infantry}
    node [base] (V) [right = 1.8cm of Y] {V\\Artillery}
    (U) edge[bend left] node[above] {$\alpha(t)$} (X)
    (X) edge[bend left] node[above] {$b(t)$} (Y)
    (Y) edge[bend left] node[above] {$a(t)$} (X)
