Graphics, Figures & Tables

Hello guys,
thanks in advance first of all helping me with this topic. Here is my current problem now. I need for my bachelor paper some help. Currently I have big problems dealing with reference of figures. Im splitting all my chapters in own .tex files and the current problem is this. This is an example in dummy version.

I have a text~\ref{fig:test} and so on blablabal

Code: Select all

\begin{figure}[H]
    \centering
    \includegraphics{xxx/yyy/test}
    \caption{xxx}
    \label{fig:test}
\end{figure}

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

What im doing here is to call a reference on the upcomming figure, which is defined with float, because I want to have the figure exactly at that point. Problem is now, that if i add parameters to scale the graphic, my reference automatically doesnt work and in my PDF file ?? appears. Sorry for my bad English, I hope you can understand.

Kind Regards,
wishotz

Welcome to LC

Posting fragments of code is not really helpful. In any case, your code should work if you recompile twice, the label command is placed correctly after the caption macro.

In addition, your fragment does not show any of the mentioned 'scaling' code for the graphics.

I recompiled many times before I make a change since I understand the cross reference. I think im definetly fine with the Syntax. Usually I add something like [scale=0.5] as parameter of incluegraphics, but i left it this time because I wouldn't get the reference successfully. If I add this, it commits a warning which says "Reference 'fig:test' on page X is undefined

This 'dummy' document works for me out of the box, using some arbitrary image file...

The references work as well, in addition I suggest to use the cleveref package (not done in my example, however, for sake of simplicity)

Important to mention is, that the documentclass is in my main file. All other stuff are located in packages.tex. The figure which I want to create is a chapter in a seperated file.

Well, the documentclass should be of course in the main file, however, your example does not show how you 'generate' the figure at all (I suppose that you are actually trying to place the figure with \includegraphics, not generating it.

The usage of \RequirePackage is possible within documents, but not recommended. Use \usepackage

And consider whether you really need both titlesec and tocloft -- usually they do not like each other!

The graphic which should be placed is a pdf file, so it has a better resolution

The reason for your problem is

\let\clearpage\relax

This screws up the whole referencing system.

If you don't want a new page for a separate file, use \input{foo} instead of \include{foo}

Could you explain me this? I dont really understand this. It would be nice since I want to understand the problem aswell.
I want for each chapter a seperate file, thats why i did include.

You're using article -- there are no chapters in an article.

You could get the same with \input without screwing up the system by letting a global \clearpage go into nirvana ...
