Graphics, Figures & Tables ⇒ Caption for Figure not possible

[leonardo1979]

Dear Tex experts,

I am trying to add a caption for a graphic generated using tikZ. I tried to use

Code: Select all

\begin{figure} 
% HERE the commands to generate my graphic
\caption{My caption}
\end{figure}

...but it is not working. the commands that I tried to use are as comments.
Where is my mistake? (I use Windows 7, WinEdt 6.0 and MiKTeX 2.8)

Code: Select all

\documentclass{minimal}
\usepackage[a4paper,margin=1cm,landscape]{geometry}
\usepackage{tikz}
\usepackage{graphicx}
\usepackage{caption}

 \usetikzlibrary{positioning,shadows,arrows}
\begin{document}
\vspace*{\fill}
%\begin{figure}
\begin{tikzpicture}[

level 2/.style={sibling distance=28mm},
level 3/.style={sibling distance=20mm},

    fact/.style={rectangle, draw=none, rounded corners=1mm, fill=blue, drop shadow,
        text centered, anchor=north, text=white},

Thanks in advance for your attention.

Hi Leo,

it doesn't work because you used the minimal class, which doesn't provide a {figure} environment. With article or book, for example, it would work. Btw. \vspace*{\fill} is not needed if you use a figure environment, it's not meaningful since figures are floating objects.

Don't use the minimal class just because you don't want to create a small example, since many commands from standard classes are simply not defined. It's more like a test class for developer.
