I have the following lines:
\begin{figure}[htbp]
\label{fig:sampleconfig}
\begin{center}
\begin{tikzpicture}[level distance=1.5cm, grow=down,
every node/.style={minimum size=1cm,circle,thin,draw},
edge from parent/.style={-latex, thin, draw}
]
\node {$A$}
child {
node {$CO_{1}$}
child {node[rectangle,draw] {$CL_{1}$}}
}
child {
node[circle,dotted,draw] {$\cdots$}
child {node[rectangle,dotted,draw] {$\cdots$}}
}
child {
node {$CO_{n}$}
child {node[rectangle,draw] {$CL_{n}$}}
}
;
\end{tikzpicture}
\caption{Sample configuration}
\end{center}
\end{figure}
In Figure ~\ref{fig:sampleconfig}, the node labelled $A$ is the root APPLICATION node.
No matter how many times I recompile the LaTeX file, I still get two question marks in place of "Figure 1," like so: "Figure ??."
Am I doing something incorrectly?
Thanks in advance for your help.
EDIT
In case it would help to solve the problem: I'm using MikTex 2.9 on Windows 7.
\label
command must go after the\caption
(or inside its argument). Besides you shouldn't be using thecenter
environment, but rather the simple command\centering
in place of\begin{center}
label{}
command, see this related question: tex.stackexchange.com/q/377685/61946
