General ⇒ Label and reference issue

[crod]

Hello fellow latex users.

I have a problem regarding the cross referencing of my images. I want to include the section number. Say for instance I write \label{fig:image} AFTER the \caption tag in a inserted image. I reference it and get the number of my figure to 4. But if I want to include the section number aswell eg instead of just figure 4, I want figure 11-4 denoting section 11 figure 4 in that section.

Any ideas?

If you just want to include a reference to the section number, then

Code: Select all

\section{my section header} \label{sec:mysec}

will produce a label such that \ref{sec:mysec} will return its number.

If, instead, you want all figure numbers to automatically be numbered N-M, where N is the section number and M is the figure number, try

Code: Select all

\numberwithin{figure}{section}

You'll need the amsmath package.

The default is to separate them by periods. If you want hyphens, you'll have to redefine \thefigure, like so:

Code: Select all

\renewcommand{\thefigure}{\thesection-\arabic{figure}

This is basically what \numberwithin does anyway.
