I'm typesetting an article using PNAS' template for two-column articles: http://www.pnas.org/misc/PNASTWO.CLS

My problem is that if I include a figure or table:

\caption{my figure}

and reference my figure or table,

I now reference Figure \ref{fig:myfig}, a decent figure

the Figure number does not appear:

I now reference Figure , a decent figure

However, if I specify float placement with the


option, the number appears:

I now reference Figure 1, a decent figure

[tbh], [thbp] will not work, but all variants starting with [h] give float number, like [htb]. Pdflatex does not give any warnings when the float reference do not show, not even the normal ??.

The problem with using [h] is that the [h] figure placement is sub-optimal, making my article longer than the 6-page limit for PNAS.

The pnastwo.cls style file is behind this somehow, because when using a normal article style the reference numbers appear.

I'm not asking anyone to correct the pnas style file, but I would be glad if anyone has any ideas about what is happening here.

    Very hard to tell since we do not know what pnastwo.cls is. Perhaps someone has done something not particularly clever. Try \caption{bla bla\label{fig}}, some journal styles does not comply to standard LaTeX – daleif Dec 13 '12 at 11:47
  • Can you provide a complete minimal document showing the problem. When I try to put one together, I have no problems with numbering and references to the figures. – Andrew Swann Dec 13 '12 at 11:51
  • daleif: Your suggestion worked! Putting the label within the caption solved the issue! Thanks! – Jorgen Dec 13 '12 at 12:00
  • Sigh ........ :-) – daleif Dec 13 '12 at 13:01
  • Worked for me with placing the \label after \caption{}, too... – clemens Dec 13 '12 at 20:12
