Graphics, Figures & Tables ⇒ Weird figure numbering

[Xorlium]

Hello,

I have no idea what is going on here. I've reduced it to a minimal example:

Code: Select all

Code, edit and compile here:

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
\pdfoptionpdfminorversion=5
\documentclass[12pt]{article}
\usepackage{amsmath}
\usepackage[demo]{graphicx}
\usepackage{float}
\usepackage{hyperref}
\begin{document}
\section{Intro}
Intro section to show whatever...
\section{Whatever}\label{definitelyNOTouch}
The following should read Figure 1: Figure~\ref{ouch}
But it reads Figure 2!! What is going on???
\begin{figure}[H] \label{ouch}
\begin{center}
\includegraphics{anypic.pdf}
\caption{Some nice caption}
\end{center}
\end{figure}
\end{document}

Run LaTeX here

Just see what happens. I compile it and it calls the figure "figure 1", but it refers to it as "Figure 2"!! And the link points to the section 2, not figure 1.

I've tried cleaning the help files and recompiling thousands of times, so that's not it. I've also tried this in a different computer with a different OS.

Thanks!

Hi,

welcome to the board!

Just use \label after \caption, this order is important. You will see, it will work fine then. \caption prepares an internal macro which can be used by \label. Without it, \label refers to the anchor before, which is the section here, that's why you got the number 2.

By the way, by simply adding the demo option to graphicx you can ensure that people are able to compile it even without the image. I edited the code line above for you. Now readers can just click the "Open" link above the code and see the output. That's why it's great that you posted a minimal example.

The \label needs to be placed after \caption, otherwise it will reference to the last command which had produced a reference which is \section{Whatever} here.

Ah, thanks! It works now

[sabbaumt]

\newpage
\section{Electrospun nanofibers as host scaffold for the growth of hierarchical nanostructures}
\begin{figure}[ht]
\centering
\includegraphics[width=0.9\textwidth]{D:/Dharani/Theisis/Thesis/Figures/14.png}
\caption[blah.]{blah.}
\label{fig:14}
\end{figure}

I used the above format and for section 1 it worked but for section 2 it didnt work, it always recalls the image as Fig. 2.2. I dont understand whats going wrong.
Can you please help me?

Impossible to tell the reason for the behaviour described. The safest way to find the problem cause, is to prepare a minimal working example and come back here.

Another thing, do you know the difference between \newpage and \clearpage? Maybe the latter is of more use for you.

Best regards
Johannes

BTW: Please insert code into the code-environment, this gives nice markup.

I had the same problem you were mentioning before.

I could find a solution by just disabling the \centering option, like this (with the "%" symbol):

\newpage
\section{Electrospun nanofibers as host scaffold for the growth of hierarchical nanostructures}
\begin{figure}[ht]
%\centering
\includegraphics[width=0.9\textwidth]{D:/Dharani/Theisis/Thesis/Figures/14.png}
\caption[blah.]{blah.}
\label{fig:14}
\end{figure}

It worked perfectly to me. All the references and ordinal numbers for my figures were right!

[Ijon Tichy]

\centering does not influence labels or references. Please show a minimal working example.

BTW: You should not use the center environment inside a float like figure or table, because it does add extra vertical space. An indeed if you would use center, the \label has to be in the same group level as the \caption.
